I try to validate XDocument with compiled (and correct) schema set and with providing post validation schema info (PVSI):
public void ValidateDoc(XDocument doc)
{
if (doc == null)
return;
// _schema is correct filled schema-set
if (!_schemas.IsCompiled)
_schemas.Compile();
try
{
_validated.Clear();
if (_schemas.Count > 0)
doc.Validate(_schemas, OnValidate, true);
foreach (var item in _validated)
{
var si = item.GetSchemaInfo();
// si exists and si.Validity is set to XmlSchemaValidity.Invalid but si.SchemaElement and si.SchemaAttribute is null
}
}
catch (XmlSchemaException err)
{
_log.FatalException(string.Format("Failed to validate document {0} [{1}, {2}] ", doc.BaseUri, err.LineNumber, err.LinePosition), err);
}
}
protected virtual void OnValidate(object sender, ValidationEventArgs args)
{
if (ValidationEvent != null)
ValidationEvent(sender, args);
var xobj = sender as XObject;
if (xobj != null)
{
xobj.AddAnnotation(new XmlErrInfo(args));
if (xobj is XElement)
_validated.Add((XElement)xobj);
}
}
But .GetSchemaInfo().SchemaElement is null (and other fields its empty too), instead of point to compiled schema element (I need to use it in future validation scenarios of same elements). What's wrong with it or what I doing wrong?
Well if you wanted to access the SchemaElement of valid elements I could understand your approach but you seem to want to access the SchemaElement of those invalid elements reported to the event handler. I don't think those properties are populated for invalid nodes.

I have inherited an older customization to the Purchase Receipts / PO302000 screen that I'm trying to upgrade, and it had customization code to import Lot/Serial nbrs from an Excel spreadsheet. It all seems to work alright, except that at the end, it errors out when pressing a button as follows:
Base.Actions["LSPOReceiptLine_binLotSerial"].Press();
Here's the entire code:
public virtual void importAllocations()
{
try
{
if (Base.transactions.Current != null)
{
var siteid = Base.transactions.Current.SiteID;
if (Base.splits.Select().Count == 0)
{
if (this.NewRevisionPanel.AskExt() == WebDialogResult.OK)
{
const string PanelSessionKey = "ImportStatementProtoFile";
PX.SM.FileInfo info = PX.Common.PXContext.SessionTyped<PXSessionStatePXData>().FileInfo[PanelSessionKey] as PX.SM.FileInfo;
System.Web.HttpContext.Current.Session.Remove(PanelSessionKey);
if (info != null)
{
byte[] filedata = info.BinData;
using (NVExcelReader reader = new NVExcelReader())
{
Dictionary<UInt32, string[]> data = reader.loadWorksheet(filedata);
foreach (string[] textArray in data.Values)
{
if (textArray[0] != GetInventoryCD(Base.transactions.Current.InventoryID))
{
throw (new Exception("InventoryID in file does not match row Inventory ID"));
}
else
{
//Find the location ID based on the location CD provided by the Excel sheet...
INLocation inloc = PXSelect<INLocation,
Where<INLocation.locationCD, Equal<Required<INLocation.locationCD>>,
And<INLocation.siteID, Equal<Required<INLocation.siteID>>>>>.Select(Base
, textArray[1]
, Base.transactions.Current.SiteID);
Base.splits.Insert(new POReceiptLineSplit()
{
InventoryID = Base.transactions.Current.InventoryID,
LocationID = inloc.LocationID, //Convert.ToInt32(textArray[1]), //Base.transactions.Current.LocationID,
LotSerialNbr = textArray[2],
Qty = Decimal.Parse(textArray[3])
});
}
}
}
}
}
}
}
Base.Actions["LSPOReceiptLine_binLotSerial"].Press();
}
catch (FileFormatException fileFormat)
{
// Acuminator disable once PX1053 ConcatenationPriorLocalization [Justification]
throw new PXException(String.Format("Incorrect file format. File must be of type .xlsx", fileFormat.Message));
}
catch (Exception ex)
{
throw ex;
}
}
Now, there seems to be no such button - and I have no idea what it would be called now, or if it even still exists. I don't even really know what this action did.
Any ideas?
Thanks much...
That logic has been moved into the PX.Objects.PO.GraphExtensions.POReceiptEntryExt.POReceiptLineSplittingExtension. That action was doing the following in the PX.Objects.PO.LSPOReceiptLine
// PX.Objects.PO.LSPOReceiptLine
// Token: 0x0600446F RID: 17519 RVA: 0x000EE86C File Offset: 0x000ECA6C
public override IEnumerable BinLotSerial(PXAdapter adapter)
{
if (base.MasterCache.Current != null)
{
if (!this.IsLSEntryEnabled((POReceiptLine)base.MasterCache.Current))
{
throw new PXSetPropertyException("The Line Details dialog box cannot be opened because changing line details is not allowed for the selected item.");
}
this.View.AskExt(true);
}
return adapter.Get();
}
Now it is called ShowSplits and is part of the POReceiptLineSplittingExtension extension.
// PX.Objects.PO.GraphExtensions.POReceiptEntryExt.POReceiptLineSplittingExtension
// Token: 0x06005359 RID: 21337 RVA: 0x00138621 File Offset: 0x00136821
public override IEnumerable ShowSplits(PXAdapter adapter)
{
if (base.LineCurrent == null)
{
return adapter.Get();
}
if (!this.IsLSEntryEnabled(base.LineCurrent))
{
throw new PXSetPropertyException("The Line Details dialog box cannot be opened because changing line details is not allowed for the selected item.");
}
return base.ShowSplits(adapter);
}
Given the fact that ShowSplits is defined in the LineSplittingExtension originally it may be referred to as "LineSplittingExteions_ShowSplits" or "POReceiptLineSplittingExtension_ShowSplits". I would suggest including that POReceiptLineSplittingExtension as part of your extension and simply call the Base1.ShowSplits
I try to put a file into a richtext but it crashes !
In my first code, I try to use directly "getFirstItem", in first time it was ok but now i try to use it again and it crashed.
In second time i pass with an object and it find my obj doesn't an richtextItem (instanceof) ???
I don't understand.
I have the message : "lotus.domino.local.Item cannot be cast to lotus.domino.RichTextItem" ?
Could you help me ?
public void copieFichierDansRichText(String idDocument, String nomRti, File file,
String nameFichier, String chemin) throws NotesException {
lotus.domino.Session session = Utils.getSession();
lotus.domino.Database db = session.getCurrentDatabase();
lotus.domino.Document monDoc = db.getDocumentByUNID(idDocument);
lotus.domino.RichTextItem rtiNew = null;
try {
try {
if (monDoc != null) {
// if (monDoc.getFirstItem(nomRti) != null) {
// rtiNew = (lotus.domino.RichTextItem)
// monDoc.getFirstItem(nomRti);
// } else {
// rtiNew = (lotus.domino.RichTextItem)
// monDoc.createRichTextItem(nomRti);
// }
Object obj = null;
if (monDoc.getFirstItem(nomRti) != null) {
obj = monDoc.getFirstItem(nomRti);
if (obj instanceof lotus.domino.RichTextItem) {
rtiNew = (lotus.domino.RichTextItem) obj;
}
} else {
obj = monDoc.createRichTextItem(nomRti);
if (obj instanceof lotus.domino.RichTextItem) {
rtiNew = (lotus.domino.RichTextItem) obj;
}
}
PieceJointe pieceJointe = new PieceJointe();
pieceJointe = buildPieceJointe(file, nameFichier, chemin);
rtiNew.embedObject(EmbeddedObject.EMBED_ATTACHMENT, "", pieceJointe.getChemin()
+ pieceJointe.getNomPiece(), pieceJointe.getNomPiece());
monDoc.computeWithForm(true, false);
monDoc.save(true);
}
} finally {
rtiNew.recycle();
monDoc.recycle();
db.recycle();
session.recycle();
}
} catch (Exception e) {
e.printStackTrace();
}
}
EDIT : I try to modify my code with yours advices but the items never considerate as richtextitem. It is my problem. I don't understand why, because in my field it is a richtext ! For it, the item can't do :
rtiNew = (lotus.domino.RichTextItem) item1;
because item1 not be a richtext !!!
I was trying to take all the fields and pass in the item one by one, and it never go to the obj instance of lotus.domini.RichTextItem....
Vector items = doc.getItems();
for (int i=0; i<items.size(); i++) {
// get next element from the Vector (returns java.lang.Object)
Object obj = items.elementAt(i);
// is the item a RichTextItem?
if (obj instanceof RichTextItem) {
// yes it is - cast it as such // it never go here !!
rt = (RichTextItem)obj;
} else {
// nope - cast it as an Item
item = (Item)obj;
}
}
A couple of things. First of all I would set up a util class method to handle the object recycling in a neater way:
public enum DominoUtil {
;
public static void recycle(Base... bases) {
for (Base base : bases) {
if (base != null) {
try {
base.recycle();
} catch (Exception e) {
// Do nothing
}
}
}
}
}
Secondly I would remove the reduntants try/catch blocks and simplify it like this:
private void copieFichierDansRichText(String idDocument, String nomRti, File file,
String nameFichier, String chemin) {
Session session = DominoUtils.getCurrentSession();
Database db = session.getCurrentDatabase();
Document monDoc = null;
try {
monDoc = db.getDocumentByUNID(idDocument);
Item item = monDoc.getFirstItem(nomRti);
if (item == null) {
item = monDoc.createRichTextItem(nomRti);
} else if (item.getType() != Item.RICHTEXT) {
// The item is not a rich text item
// What are you going to do now?
}
RichTextItem rtItem = (RichTextItem) item;
PieceJointe pieceJointe = new PieceJointe();
pieceJointe = buildPieceJointe(file, nameFichier, chemin);
rtItem.embedObject(EmbeddedObject.EMBED_ATTACHMENT, "", pieceJointe.getChemin()
+ pieceJointe.getNomPiece(), pieceJointe.getNomPiece());
monDoc.computeWithForm(true, false);
monDoc.save(true);
} catch (NotesException e) {
throw new FacesException(e);
} finally {
DominoUtil.recycle(monDoc);
}
}
Finally, apart from the monDoc, you need not recycle anything else. Actually Session would be automatically recycled and anything beneath with it (so no need to recycle db, let alone the session!, good rule is don't recycle what you didn't instantiate), but it's not bad to keep the habit of keeping an eye on what you instantiate. If it were a loop with many documents you definitively want to do that. If you also worked with many items you would want to recycle them as early as possible. Anyway, considered the scope of the code it's sufficient like this. Obviously you would call DominoUtil.recycle directly from the try block. If you have multiple objects you can recycle them at once possibly by listing them in the reverse order you set them (eg. DominoUtil.recycle(item, doc, view)).
Also, what I think you miss is the check on the item in case it's not a RichTextItem - and therefore can't be cast. I put a comment where I think you should decide what to do before proceeding. If you let it like that and let the code proceed you will have the code throw an error. Always better to catch the lower level exception and re-throw a higher one (you don't want the end user to know more than it is necessary to know). In this case I went for the simplest thing: wrapped NotesException in a FacesException.
I have a simple application. When a user logs in it creates a session variable and redirects them to another controller that pull up some info from the database. I need to store this to a session variable then return it to the view. The initial part is fine, it returns it and I see the information. However, when I try to create a search query it returns that the session is null even though I never clear it.
public ActionResult ShowCourses()
{
if (Session["Username"] != null)
{
string Username = Session["Username"].ToString();
using (DefaultConnection db = new DefaultConnection())
{
var model = from c in db.Courses
where c.Username == Username
select c;
Session["Courses"] = model.ToList();
var Courses = Session["Courses"];
return View(Courses);
}
}
else
{
return RedirectToAction("Login", "Users");
}
}
But when I try to run a search query to loop through the session, it brings back that Courses is null. The problem is that coursesQuery returns null and I'm not sure why.
public ActionResult SearchCourses(string query)
{
if (Session["Username"] != null)
{
var coursesQuery = Session["Courses"] as IEnumerable<Course>;
if (coursesQuery != null)
{
// Do Something
}
}
}
You did a .ToList() on the course colleciton before setting to Session.
Try this. Use List<Course> when you read it back.
if (Session["Courses"] != null)
{
var coursesQuery = (List<Course>) Session["Courses"];
}
I'm trying to filter some records using the RecordFilter interface. In my app I have a couple of interfaces similar to this one, on which the user can enter an ID or Name (he/she could enter both or neither of them too)
Here's what I've done so far:
The Customer filter.
Here if the user didn't enter an ID, I pass 0 as a default value, that's why I evaluate customerID!=0
public class CustomerFilter implements RecordFilter {
private String mName_Filter;
private int mID_Filter;
public CustomerFilter(String name_Filter, int id_Filter) {
this.mName_Filter = name_Filter.toLowerCase();
this.mID_Filter = id_Filter;
}
public boolean matches(byte[] candidate) {
try {
ByteArrayInputStream bis = new ByteArrayInputStream(candidate);
DataInputStream dis = new DataInputStream(bis);
int customerID = dis.readInt();
String customerName = dis.readUTF().toLowerCase();
if ((customerName != null && customerName.indexOf(mName_Filter) != -1) && (customerID != 0 && customerID == mID_Filter))
return true;
if (customerName != null && customerName.indexOf(mName_Filter) != -1 && customerID == 0)
return true;
if (customerName == null && (customerID != 0 && customerID == mID_Filter))
return true;
if (customerName == null && customerID == 0)
return true;
} catch (IOException ex) {
//What's the point in catching a exception here???
}
return false;
}
}
The search method:
Note: This method is in a class that I call "RMSCustomer", in which I deal with everything related to RMS access. The search method receives two parameters (id and name) and uses them to instantiate the filter.
public Customer[] search(int id, String name) throws RecordStoreException, IOException {
RecordStore rs = null;
RecordEnumeration recEnum = null;
Customer[] customerList = null;
try {
rs = RecordStore.openRecordStore(mRecordStoreName, true);
if (rs.getNumRecords() > 0) {
CustomerFilter filter = new CustomerFilter(name, id);
try {
recEnum = rs.enumerateRecords(filter, null, false);
if (recEnum.numRecords() > 0) {
customerList = new Customer[recEnum.numRecords()];
int counter = 0;
while (recEnum.hasNextElement()) {
Customer cust;
int idRecord = recEnum.nextRecordId();
byte[] filterRecord = rs.getRecord(idRecord);
cust = parseRecord(filterRecord);
cust.idRecord = idRecord;
customerList[counter] = cust;
counter++;
}
}
else{
customerList = new Customer[0];
//How to send a message to the midlet from here
//saying something like "No Record Exists.Please select another filter"
}
} finally {
recEnum.destroy();
}
}
else{
//How to send a message to the midlet from here
//saying something like "No Record Exists.Please Add record"
}
} finally {
rs.closeRecordStore();
}
return customerList;
}
Even though, the code shown above works I still have some questions/problems:
In the Filter :
1) How can I improve the code that evaluates the possible values of the filters (name,id)? What if I had more filters?? Will I have to test all the possible combinations??
2) If the user doesn’t enter neither a ID nor a name, should I display all the records or should I display a message "Please enter a name or ID"?? What would you do in this case?
3) Why do I have to put a try-catch in the filter when I can't do anything there?? I can't show any alert from there or can I?
In the search method:
1) How can I show a proper message to the user from that method? something like "No records" (see the "ELSE" parts in my code
Sorry If I asked too many questions, it's just that there's any complete example of filters.
Thanks in advance
How can I improve the code that evaluates the possible values of the
filters (name,id)?
The ID is the first field in the record and the fastest one to search for. If the Id matches, It doesn't really matter what the customer name is. Normally you'll be looking for the records where the ID matches OR the customer name matches, so once the ID matches you can return true. This is my proposal for the CustomerFilter class:
public class CustomerFilter implements RecordFilter {
private String mName_Filter;
//Use Integer instead of int.
//This way we can use null instead of zero if the user didn't type an ID.
//This allows us to store IDs with values like 0, -1, etc.
//It is a bit less memory efficient,
//but you are not creating hundreds of filters, are you? (If you are, don't).
private Integer mID_Filter;
public CustomerFilter(String name_Filter, Integer id_Filter) {
this.mName_Filter = normalizeString(mName_Filter);
this.mID_Filter = id_Filter;
}
//You should move this function to an StringUtils class and make it public.
//Other filters might need it in the future.
private static String normalizeString(final String s){
if(s != null){
//Warning: you might want to replace accentuated chars as well.
return s.toLowerCase();
}
return null;
}
public boolean matches(byte[] candidate) {
ByteArrayInputStream bis = new ByteArrayInputStream(candidate);
DataInputStream dis = new DataInputStream(bis);
try {
if(mID_Filter != null){
//If the ID is unique, and the search is ID OR other fields, this is fine
int customerID = dis.readInt();
if(mID_Filter.intValue == customerID){
return true;
} else {
return false;
}
}
if(mName_Filter != null){
String customerName = normalizeString(dis.readUTF());
if(customerName != null && customerName.indexOf(mName_Filter) != -1){
return true;
}
}
if(mID_Filter == null && mName_Filter == null){
return true; // No filtering, every record matches.
}
} catch (IOException ex) {
//Never swallow exceptions.
//Even if you are using an underlying ByteArrayInputStream, an exception
//can still be thrown when reading from DataInputStream if you try to read
//fields that do not exists.
//But even if no exceptions were ever thrown, never swallow exceptions :)
System.err.println(ex);
//Optional: throw ex;
} finally {
//Always close streams.
if(bis != null){
try {
bis.close();
} catch(IOException ioe){
System.err.println(ioe);
}
}
if(dis != null){
try {
dis.close();
} catch(IOException ioe){
System.err.println(ioe);
}
}
}
return false;
}
}
What if I had more filters?? Will I have to test all the possible
combinations??
It depends on your project. Usually the ID is unique and no two records exist with the same id. In this case you should explicitly design the screen so that the user understands that either he types an Id, or else he fills in the other fields. The condition would be like this:
idMatches OR (field1Matches AND field2Matches AND ... fieldNMatches)
If the user types nothing, then all records will be returned.
But then again this is more a UX issue, I don't know if it is valid for your requirements.
From the programming point of view, what is clear is that the more fields you add, the more messy your filter will became. To prevent this, you could use patterns like Decorator, Composite, and even Chain of responsibility. You'll probably have to trade good design for performance though.
If the user doesn’t enter neither a ID nor a name, should I display
all the records or should I display a message "Please enter a name or
ID"?? What would you do in this case?
It depends. Is there any other way to view all records? If so, then show the message.
Why do I have to put a try-catch in the filter when I can't do
anything there?? I can't show any alert from there or can I?
You shouldn't. This class is only responsible of filtering, not of interacting with the user. You can still log the error from the catch clause, and then throw the exception again. That will propagate the exception up to RMSCustomer.search, so whatever client code is calling that function will handle the exception in the same way you are handling the other ones thrown by that method. But keep the finally clause to close the streams.
How can I show a proper message to the user from that method?
something like "No records" (see the "ELSE" parts in my code)
You shouldn't do anything related to the GUI (like showing dialogs) from the RMSCustomer class. Even if you are not using the Model-View-Controller pattern, you still want to keep your class focused on a single responsibility (managing records). This is called the Single responsibility principle.
Keeping your class isolated from the GUI will allow you to test it and reuse it in environments without GUI.
The no records case should be handled by the screen when there are zero results. An array of lenght == 0 is fine here, and the screen will show the "No results" message. For other kinds of errors, you can extend the Exception class and throw your own custom exceptions, i.e: RecordParsingException, from the RMSCustomer.search method. The screen class will then map the different exceptions to the error message in the language of the user.
I am attempting to retrieve objects having several attributes with the name from netscape LDAP directory with LDAP SDK from Unboundit. The problem is that only one of the attributes are returned - I am guessing LDAP SDK relays heavily on unique attribute names, is there a way to configure it to also return non-distinct attributes as well?
#Test

long currentTimeMillis = System.currentTimeMillis();
LDAPConnection connection = new LDAPConnection("xxx.xxx.xxx", 389,

"xxxx");
SearchRequest searchRequest = new SearchRequest(
"ou=xxx,ou=xx,dc=xx,dc=xx",
SearchScope.SUB, "(uid=xxx)", SearchRequest.ALL_USER_ATTRIBUTES );
LDAPEntrySource entrySource = new LDAPEntrySource(connection,
searchRequest, true);
try {
while (true) {
try {
System.out.println("*******************************************");
Entry entry = entrySource.nextEntry();
if (entry == null) {
// There are no more entries to be read.
break;
} else {
Collection<Attribute> attributes = entry.getAttributes();
for (Attribute attr : attributes)
{
System.out.println (attr.getName() + " " + attr.getValue());
}
}
} catch (SearchResultReferenceEntrySourceException e) {
// The directory server returned a search result reference.
SearchResultReference searchReference = e
.getSearchReference();
} catch (EntrySourceException e) {
// Some kind of problem was encountered (e.g., the
// connection is no
// longer valid). See if we can continue reading entries.
if (!e.mayContinueReading()) {
break;
}
}
}
} finally {
entrySource.close();
}
System.out.println("Finished in " + (System.currentTimeMillis() - currentTimeMillis));
}
Non-unique LDAP attributes are considered multivalued and are reperesented as String array.
Use Attribute.getValues() instead of attribute.getValue.
