getting a list of forms that contain a specified field, is there a better method - xpages

The following code is a script object on an XPage in it I loop through an array of all the forms in a database, looking for all the forms that contain the field "ACIncludeForm". My method works but it takes 2 - 3 seconds to compute which really slows the load of the XPage. My question is - is there a better method to accomplish this. I added code to check to see if the sessionScope variable is null and only execute if needed and the second time the page loads it does so in under a second. So my method really consumes a lot of processor time.
var forms:Array = database.getForms();
var rtn = new Array;
for (i=0 ; i<forms.length; ++i){
var thisForm:NotesForm = forms[i];
var a = thisForm.getFields().indexOf("ACIncludeForm");
if (a >= 0){
if (!thisForm.isSubForm()) {
if (thisForm.getAliases()[0] == ""){
rtn.push(thisForm.getName() + "|" + thisForm.getName() );
}else{
rtn.push(thisForm.getName() + "|" + thisForm.getAliases()[0] );
}
}
}
thisForm.recycle()
}
sessionScope.put("ssAllFormNames",rtn)

One approach would be to build an index of forms by yourself. For example, create an agent (LotusScript or Java) that gets all forms and for each form, create a document with for example a field "form" containing the form name and and a field "fields" containing all field names (beware of 32K limit).
Then create a view that displays all these documents and contains the value of the "fields" field in the first column so that each value of this field creates one line in this view.
Having such a view, you can simply make a #DbLookup from your XPage.
If your forms are changed, you only need to re-run the agent to re-build your index. The #DbLookup should be pretty fast.

Place the form list in a static field of a Java class. It will stay there for a long time (maybe until http boot). In my experience applicationScope values dissappear in 15 minutes.

Can't modify/remove a field from an ActivityNode using sbt

I created an ActivityNode (an Entry) and I can add custom fields with the
setFields(List<Field> newListField)
fonction.
BUT
I am unable to modify these fields. (In this case I try to modify the value of the field named LIBENTITE)
FieldList list = myEntry.getTextFields();
List<Field> updatedList = new ArrayList<Field>();
//I add each old field in the new list, but I modify the field LIBENTITE
for(Field myField : list){
if(myField.getName().equals("LIBENTITE")){
((TextField)myField).setTextSummary("New value");
}
updatedList.add(myField);
}
myEntry.setFields(updatedList);
activityService.updateActivityNode(myEntry);
This code should replace the old list of fields with the new one, but I can't see any change in the custom field LIBENTITE of myEntry in IBM connections.
So I tried to create a new list of fields, not modifying my field but adding a new one :
for(Field myField:list){
if(!myField.getName().equals("LIBENTITE")){
updatedList.add(myField);
}
}
Field newTextField = new TextField("New Value");
newTextField .setFieldName("LIBENTITE");
updatedList.add(newTextField );
And this code is just adding the new field in myEntry. What I see is that the other custom fields did not change and I have now two custom fields named LIBENTITE, one with the old value and the second with the new value, in myEntry.
So I though that maybe if I clear the old list of Fields, and then I add the new one, it would work.
I tried the two fonctions
myEntry.clearFieldsMap();
and
myEntry.remove("LIBENTITE");
but none of them seems to work, I still can't remove a custom field from myEntry using SBT.
Any suggestions ?
I have two suggestions, as I had (or have) similar problems:
If you want to update an existing text field in an activity node, you have to call node.setField(fld) to update the field in the node object.
Code snippet from my working application, where I'm updating a text field containing a (computed) start time:
ActivityNode node = activityService.getActivityNode(id);
node.setTitle(formatTitle()); // add/update start and end time in title
boolean startFound = false;
// ...
FieldList textfields =node.getTextFields();
Iterator<Field> iterFields = textfields.iterator();
while (iterFields.hasNext()) {
TextField fld = (TextField) iterFields.next();
if (fld.getName().equals(Constants.FIELDNAME_STARTTIME)) {
fld.setTextSummary(this.getStartTimeString()); // NOTE: .setFieldValue does *not* work
node.setField(fld); // write updated field back. This seems to be the only way updating fields works
startFound=true;
}
}
If there is no field with that name, I create a new one (that's the reason I'm using the startFound boolean variable).
I think that the node.setField(fld) should do the trick. If not, there might be a way to sidestep the problem:
You have access to the underlying DOM object which was parsed in. You can use this to tweak the DOM object, which finally will be written back to Connections.
I had to use this as there seems to be another nasty bug in the SBT SDK: If you read in a text field which has no value, and write it back, an error will be thrown. Looks like the DOM object misses some required nodes, so you have to create them yourself to avoid the error.
Some code to demonstrate this:
// ....
} else if (null == fld.getTextSummary()) { // a text field without any contents. Which is BAD!
// there is a bug in the SBT API: if we read a field which has no value
// and try to write the node back (even without touching the field) a NullPointerException
// will be thrown. It seems that there is no value node set for the field. We
// can't set a value with fld.setTextSummary(), the error will still be thrown.
// therefore we have to remove the field, and - optionally - we set a defined "empty" value
// to avoid the problem.
// node.remove(fld.getName()); // remove the field -- this does *not* work! At least not for empty fields
// so we have to do it the hard way: we delete the node of the field in the cached dom structure
String fieldName = fld.getName();
DeferredElementNSImpl fldData = (DeferredElementNSImpl) fld.getDataHandler().getData();
fldData.getParentNode().removeChild(fldData); // remove the field from the cached dom structure, therefore delete it
// and create it again, but with a substitute value
Field newEmptyField = new TextField (Constants.FIELD_TEXTFIELD_EMPTY_VALUE); // create a field with a placeholder value
newEmptyField.setFieldName(fieldName);
node.setField(newEmptyField);
}
Hope that helps.
Just so that post does not stay unanswered I write the answer that was in a comment of the initial question :
"currently, there is no solution to this issue, the TextFields are read-only map. we have the issue recorded on github.com/OpenNTF/SocialSDK/issues/1657"

Can't set Orchard field values unless item already created

I seem to be having a problem with assigning values to fields of a content item with a custom content part and the values not persisting.
I have to create the content item (OrchardServices.ContentManager.Create) first before calling the following code which modifies a field value:
var fields = contentItem.As<MyPart>().Fields;
var imageField = fields.FirstOrDefault(o => o.Name.Equals("Image"));
if (imageField != null)
{
((MediaLibraryPickerField)imageField).Ids = new int[] { imageId };
}
The above code works perfectly when against an item that already exists, but the imageId value is lost if this is done before creating it.
Please note, this is not exclusive to MediaLibraryPickerFields.
I noticed that other people have reported this aswell:
https://orchard.codeplex.com/workitem/18412
Is it simply the case that an item must be created prior to amending it's value field?
This would be a shame, as I'm assigning this fields as part of a large import process and would inhibit performance to create it and then modify the item only to update it again.
As the comments on this issue explain, you do need to call Create. I'm not sure I understand why you think that is an issue however.

Setting a document field with replaceItemValue from a rich text control?

How do you set a richText value with replaceItemValue from a rich tect control?
I found this bit of code here:
http://www.bleedyellow.com/blogs/martin/entry/save_a_richtext_field_from_a_xpage_to_a_document?lang=en_us
var doc = configuratieformulieren.getDocumentByKey("ConfiguratieIVNL", true);
if(doc == null){
return;
}else{
var titel = getComponent("inputTextIBPTitelIVNL").getValue();
doc.replaceItemValue("IBPTitel",titel);
var inhoud = getComponent("inputRichTextIBPInhoudIVNL").getValue();
if (inhoud != null){
var contentType = doc.getMIMEEntity("IBPInhoud").getContentType();
var encoding = doc.getMIMEEntity("IBPInhoud").getEncoding();
var str = session.createStream();
inhoud.toString();
str.writeText(inhoud.toString());
doc.getMIMEEntity("IBPInhoud").setContentFromText(str, contentType, encoding);
}
doc.save(true, true);
}
sessionScope.put("FormulierIVNLInfoBeschPG","Lezen");
Is it correct? It looks like this code depends on the fact that the field already exists. How id this handled if the field does not exist? Is there and easier way to set a field value to the contents of a rich text control?
Let data sources do the heavy lifting. For a long and boring (but thorough) explanation of why, read this article. But here's the quick version:
Don't use:
getComponent("someID").getValue()
Instead, use:
someDataSource.getValue("someFieldName")
This is always a more efficient way to access data: instead of having to spider through the component tree to locate a match, it goes straight to the data source, which the component would have to ask anyway if you asked it what its value is.
Similarly, don't use:
someDataSource.replaceItemValue("someFieldName", someValue)
Instead, use:
someDataSource.setValue("someFieldName", someValue)
The latter is much more flexible on input type. The data source already contains all the logic for determining what to do based on whether the value is text, date, number, rich text, file upload, etc. No need to duplicate any of that logic in your own code.
So if the goal is to update a separate document based on data in the current document, just define a separate document data source that points to the document you want to update. Then it's literally this simple:
configData.setValue("RichTextData", currentDocument.getValue("RichTextData"));
configData.save();
With the above code, if the field you specify on the current document is rich text, then the item it creates on the other document will be rich text. If it's any other type on the current document, it will be the same type on the other document. With getValue() and setValue(), you don't have to pay attention to the data type... the data source handles all of that for you.
For bonus points, scope configData to applicationScope so that any updates to it are immediately cached for all users... or sessionScope if the document you're updating is user-specific.
I was able to solve my orginal issue. To expand on my issue I was having problems with using a dialog box to create Form / Document B from Form / Document A using a dialog box on Form A. What was happening was any changes to Form B would be saved to Document A's datasource.
I found the ingoreRequestParams on Form B's datasource, set it and that solved my problem with Form B writing to Form A document.

Binding an edit box within a custom control to a form field programatically

I have a notes form with a series of fields such as city_1, city_2, city_3 etc.
I have an XPage and on that XPage I have a repeat.
The repeat is based on an array with ten values 1 - 10
var repArray = new Array() ;
for (var i=1;i<=10;i++) {
repArray.push(i) ;
}
return(repArray) ;
Within the repeat I have a custom control which is used to surface the fields city_1 through city_10
The repeat has a custom property docdatasource which is passed in
It also has a string custom property called cityFieldName which is computed using the repeat
collection name so that in the first repeat row it is city_1 and in the second it is city_2 etc..
The editable text field on the custom control is bound using the EL formula
compositeData.docdatasource[compositeData.cityFieldName]
This works fine but each time I add new fields I have to remember to create a new custom property and then a reference to it on the parent page.
I would like to be able to simply compute the data binding such as
compositeData.docdatasource['city_' + indexvar]
where indexvar is a variable representing the current row number.
Is this possible ? I have read that you cannot use '+' in Expression Language.
First: you wouldn't need an array for a counter. Just 10 would do (the number) - repeats 10 times too. But you could build an array of arrays:
var repArray = [];
for (var i=1;i<=10;i++) {
repArray.push(["city","street","zip","country","planet"]) ;
}
return repArray;
then you should be able to use
#{datasource.indexvar[0]}
to bind city,
#{datasource.indexvar[1]}
to bind street. etc.
Carries a little the danger of messing with the sequence of the array, if that's a concern you would need to dig deeper in using an Object here.
compute to javascript and use something like
var viewnam = "#{" + (compositeData.searchVar )+ "}"
return viewnam
make sure this is computed on page load in the custom control
I was never able to do the addition within EL but I have been very successful with simply computing the field names outside the custom control and then passing those values into the custom control.
I can send you some working code if you wish from a presentation I gave.

How can I set the default value in a SharePoint list field, based on the value in another field?

I have a custom list in SharePoint (specifically, MOSS 2007.) One field is a yes/no checkbox titled "Any defects?" Another field is "Closed by" and names the person who has closed the ticket.
If there are no defects then I want the ticket to be auto-closed. If there are, then the "Closed by" field ought to be filled in later on.
I figured I could set a calculated default value for "Closed by" like this:
=IF([Any defects?],"",[Me])
but SharePoint complains I have referenced a field. I suppose this makes sense; the default values fire when the new list item is first opened for entry and there are no values in any fields yet.
I understand it is possible to make a calculated field based on a column value but in that case the field cannot be edited later.
Does anyone have any advice how to achieve what I am trying to do?
Is it possible to have a "OnSubmit" type event that allows me to execute some code at the point the list item is saved?
Thank you.
Include a content editor web part in the page (newform.aspx / editform.aspx) and use jQuery (or just plain javascript) to handle the setting of default values.
Edit: some example code:
In the lists newform.aspx, include a reference to jquery. If you look at the html code, you can see that each input tag gets an id based on the field's GUID, and a title that's set to the fields display name.
now, using jquery we can get at these fields using the jQuery selector like this:
By title:
$("input[title='DISPLAYNAMEOFFIELD']");
by id (if you know the field's internal guid, the dashes will ahve to be replaced by underscores:
// example field id, notice the guid and the underscores in the guid ctl00_m_g_054db6a0_0028_412d_bdc1_f2522ac3922e_ctl00_ctl04_ctl15_ctl00_ctl00_ctl04_ctl00_ctl00_TextField
$("input[id*='GUID']"); //this will get all input elements of which the id contains the specified GUID, i.e. 1 element
We wrap this in the ready() function of jQuery, so all calls will only be made when the document has fully loaded:
$(document).ready(function(){
// enter code here, will be executed immediately after page has been loaded
});
By combining these 2 we could now set your dropdown's onchange event to the following
$(document).ready(function(){
$("input[title='DISPLAYNAMEOFFIELD']").change(function()
{
//do something to other field here
});
});
The Use jQuery to Set A Text Field’s Value on a SharePoint Form article on EndUserSharePoint.com shows you how to set a default value for a field using JavaScript/jQuery.
They also have a whole series of articles on 'taming calculated columns' that will show you many more powerful options you have for calculated fields with the use of jQuery.
One thing to be aware of when inserting JavaScript into a SharePoint page and modifying the DOM is support. There is a small chance that a future service pack will break the functionality you add, and it is quite likely that the next version of SharePoint will break it. Keeping this mind however, I believe it's a good solution at this time.
I've got a walk through with sample code that may help
Setting a default duration for new calendar events
It sets the End Time/Date fields to Start Time + 1.5 hours when you create a new event.
Its complicated a little by the steps need to do the time/date work, but you'll see examples of how to find the elements on the form and also one way to get your script onto the newform.aspx without using SPD.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js">
</script>
<script type="text/javascript">

var hoursToAdd = 1;
// Mins must be 0 or div by 5, e.g. 0, 5, 10, 15 ...
var minutesToAdd = 30;
// JavaScript assumes dates in US format (MM/DD/YYYY)
// Set to true to use dates in format DD/MM/YYYY
var bUseDDMMYYYYformat = false;
$(function() {
// Find the start and end time/minutes dropdowns by first finding the
// labels then using the for attribute to find the id's
// NOTE - You will have to change this if your form uses non-standard

var cboStartHours = $("#" + $("label:contains('Start Time Hours')").attr("for"));
var cboEndHours = $("#" + $("label:contains('End Time Hours')").attr("for"));
var cboEndMinutes = $("#" + $("label:contains('End Time Minutes')").attr("for"));
// Set Hour
var endHour = cboStartHours.attr("selectedIndex") + hoursToAdd;
cboEndHours.attr("selectedIndex",endHour % 24);
// If we have gone over the end of a day then change date

else
return new Date(sDate);
}
function formatDate(dtDate)

if (bUseDDMMYYYYformat)
return dtDate.getDate() + "/" + dtDate.getMonth()+1 + "/" + dtDate.getFullYear();
else

}
