I am new in OAF. I am writing a small program for displaying data in the browser window. But as per the OAF Documentation, when a page loads processRequest() should be called automatically. But in my case the processRequest() method is not called. So any one please help me to get the processRequest() method to be called when page is loaded.
This is my Controller code. Note I associate this controller to a page. While loading the page, processRequest() method is not called.
public class MyController extends OAControllerImpl
{
public static final String RCS_ID = "$Header$";
public static final boolean RCS_ID_RECORDED =
VersionInfo.recordClassVersion(RCS_ID, "%packagename%");
/**
* Layout and page setup logic for a region.
* #param pageContext the current OA page context
* #param webBean the web bean corresponding to the region
*/
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
{
/* The below code line is used to initialize the application module */
System.out.println("inside processRequest");
OAApplicationModule am =
(OAApplicationModule)pageContext.getApplicationModule(webBean);
// am.invokeMethod("execVO");
/* The below code line is used to initialize VO*/
OAViewObject vo = (OAViewObject)am.findViewObject("EmpView1");
/* DataDisplayVO1 is the instance name in AM which is the original name of the VO */
vo.executeQuery();
RowSetIterator rowsetIterator = vo.createRowSetIterator(null);
while (rowsetIterator.hasNext())
{
Row r = rowsetIterator.next();
System.out.println("Empno is ... " + r.getAttribute("Empno"));
}
}
This is impossible. In my experience, till now I have never faced any issues like this.
On a second thought, just thinking if the controller is not assigned to the page. It may happen although in rarest case. And the case is you have run the page before attaching the controller and the page xml is stored in your classes directory. This directory is refreshed on each run, but rarely it doesn't get refreshed.
Try to rebuild your application, if possible delete the classes folder content of your relevant package. Hopefully it may help.

I have a custom module getting executed right after the PDFGenerator finished. I followed this guide on how to create a custom module
https://stackoverflow.com/a/55799101/9945420
When processing a batch document I want to manipulate the generated PDF file and add a footer to that file. The content of that footer needs to get configured in the Administration module.
So within my project called "StampOnScanProcess" I added a Folder called "Setup" with two files. A Form called "FrmSetup"
public partial class FrmSetup : Form
{
private IBatchClass batchClass;
public FrmSetup()
{
InitializeComponent();
}
public DialogResult ShowDialog(IBatchClass batchClass)
{
this.batchClass = batchClass;
// Load previous Settings ...
return this.ShowDialog();
}
private void btnCancel_Click(object sender, EventArgs e)
{
this.Close();
}
private void btnSave_Click(object sender, EventArgs e)
{
// Save ...
this.Close();
}
}
and a UserControl called "UserCtrlSetup"
[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface ISetupForm
{
[DispId(1)]
AdminApplication Application { set; }
[DispId(2)]
void ActionEvent(int EventNumber, object Argument, out int Cancel);
}
[ClassInterface(ClassInterfaceType.None)]
[ProgId(CUSTOM_MODULE_NAME_SETUP)]
public partial class UserCtrlSetup : UserControl, ISetupForm
{
private const string CUSTOM_MODULE_NAME_SETUP = "StampOnScanProcess.Setup";
private AdminApplication adminApplication;
public AdminApplication Application
{
set
{
value.AddMenu(CUSTOM_MODULE_NAME_SETUP, CUSTOM_MODULE_NAME_SETUP, "BatchClass");
adminApplication = value;
}
}
public void ActionEvent(int EventNumber, object Argument, out int Cancel)
{
Cancel = 0;
if ((KfxOcxEvent)EventNumber == KfxOcxEvent.KfxOcxEventMenuClicked && (string)Argument == CUSTOM_MODULE_NAME_SETUP)
{
FrmSetup form = new FrmSetup();
form.ShowDialog(adminApplication.ActiveBatchClass);
}
}
}
I modified my registration file and added the setup form to it
[Modules]
StampOnScanProcess
[StampOnScanProcess]
RuntimeProgram=StampOnScanProcess.exe
ModuleID=StampOnScanProcess.exe
Description=...
Version=10.2
SupportsNonImageFiles=True
SupportsTableFields=True
SetupProgram=StampOnScanProcess.Setup
[Setup Programs]
StampOnScanProcess.Setup
[StampOnScanProcess.Setup]
Visible=0
OCXFile=StampOnScanProcess.exe
ProgID=StampOnScanProcess.Setup
When launching the Administration module I head over to the Batch Class Properties => Queues and want to call this setup form by clicking the Properties button in the middle.
Unfortunately the properties button is disabled so I can't open the setup form. This form gets added to the context menu of the batch class
How can I bind this form to the properties button instead? And what is the best way to store configured data and access it when the runtime application gets executed?
I need to think about how to store data because some users have user profiles
and the runtime application currently logs in with no credentials.
public void LoginToRuntimeSession()
{
login = new Login();
login.EnableSecurityBoost = true;
login.Login();
login.ApplicationName = CUSTOM_MODULE_ID;
login.Version = "1.0";
login.ValidateUser($"{CUSTOM_MODULE_ID}.exe", false, "", "");
session = login.RuntimeSession;
}
So it might happen that I have to store the credentials on setup too.
How can I bind this form to the properties button instead?
All interactions with menu entries are handled by ISetupForm.ActionEvent. New entries are added with the AddMenu method of the AdminApplication object. Kofax differentiates between multiple entries by name - imagine that you could have multiple menu entries at the same time, one on batch class level, another one on document class level, and another one in the ribbon - just to name a few examples. Kofax uses the same approach in any component that integrates into Administration (e.g. Custom Modules or Workflow Agents).
This is an example from one of our components. Note that three entries are added on BatchClass level and two more on DocumentClass level.
value.AddMenu("BatchClass.GeneralConfig", "Field Panel - General Configuration", "BatchClass");
value.AddMenu("BatchClass.FieldEditor", "Field Panel - Configure Batch Fields", "BatchClass");
value.AddMenu("DocumentClass.FieldEditor", "Field Panel - Configure Index Fields", "DocumentClass");
value.AddMenu("CopyBatchFieldConfig", "Field Panel - Copy Batch Field Configuration", "BatchClass");
value.AddMenu("PasteBatchFieldConfig", "Field Panel - Paste Batch Field Configuration", "BatchClass");
value.AddMenu("CopyIndexFieldConfig", "Field Panel - Copy Index Field Configuration", "DocumentClass");
value.AddMenu("PasteIndexFieldConfig", "Field Panel - Paste Index Field Configuration", "DocumentClass");
Each entry is no identified by its event text, the first parameter. For example, BatchClass.GeneralConfig is intended to open up a generic configuration dialog - on batch class level.
Now, back to our ActionEvent - this is how I distinguish between the entry selected by the user:
if ((KfxOcxEvent)EventNumber == KfxOcxEvent.KfxOcxEventMenuClicked)
{
AdminForm form = new AdminForm();
switch ((string)Argument)
{
case "BatchClass.GeneralConfig":
ConfigureGeneral(kcApp.ActiveBatchClass);
break;
[I] want to call this setup form by clicking the Properties button in
the middle.
I don't know if you can use this button - I would assume yes - yet personally I tend to put settings either on batch or document class level. For example - your PDF annotation settings may different from document class to class - having an entry on this level seems more natural.
And what is the best way to store configured data and access it when
the runtime application gets executed?
Custom Storage Strings, and you can let your imagination run wild here. The most simplistic approach is to store key-value pairs during setup, and retrieve them in runtime. Here's a generic call (BatchClass is an IBatchClass object, i.e. a pointer to the ActiveBatchClass property of the AdminApplication object):
// set a CSS
BatchClass.set_CustomStorageString(name, value);
// get a CSS
BatchClass.get_CustomStorageString(name)
I usually use a single custom storage string only and store custom object - the object is a base64-encoded serialized XML using XmlSerializer - but again, that's up to you. The only recommendation is to rely on CSS only - don't use external files to store configuration parameters. A CSS is an integral part of your batch class - so, when exporting said class and importing it on a different system, your entire configuration will be there.
I need to think about how to store data because some users have user
profiles
Usually, you don't need to worry about that. The properties for user and password in ValidateUser are entirely optional - and since you're planning to write an unattended module - ideally a Windows Service, credentials should be maintained there. Kofax and Windows would automatically make sure the credentials are passed on, and your module will run under this user's context. Just make sure the user has permissions for the module and all associated batch classes. It's different if you're planning to write an attended module, for example an enhanced Validation module.
I am porting a Asp.Net MVC application to Razor Pages.
In some of the controllers of the MVC application it makes use of return View("someOtherView", someModelForOtherView);
How do I port this to Razor Pages?
What I need to do is to transfer the request over to another Razor Page and pass the prepared PageModel to it (the other page does not need to execute OnMethod() but simply render its html.
Or, in other words, I only need to swap the template file that should be rendered with another one.
I cannot use Redirect as there must not be another roundtrip via the browser.
I doubt this is (easily) possible. From the github request that Lerner linked above, it's noted Razor Pages weren't designed to do that.
The closest workaround I was able to achieve was to turn my destination Razor Page into a View. (Hence, no code-behind.) Obviously that will only be possible if your destination page is never directly accessed via URL. For example, if you want to redirect to /Pages/MyPage, and you still need to be able to access the url http://example.com/MyPage, this won't work.
But, say all you want is a generic error or status page. Those don't have to be directly-accessible through URL. This works well for that.
Here's a couple extension methods on PageModel to do it, one that accepts models and one that doesn't:
public static ViewResult View(this PageModel pageModel, string viewName) {
return new ViewResult() {
ViewName = viewName,
ViewData = pageModel.ViewData,
TempData = pageModel.TempData
};
}
public static ViewResult View<TModel>(this PageModel pageModel, string viewName, TModel model) {
var viewDataDictionary = new ViewDataDictionary<TModel>(new EmptyModelMetadataProvider(), new ModelStateDictionary()) {
Model = model
};
foreach (var kvp in pageModel.ViewData) viewDataDictionary.Add(kvp);
return new ViewResult {
ViewName = viewName,
ViewData = viewDataDictionary,
TempData = pageModel.TempData
};
}
FYI, the reason for having to recreate the view dictionary is because the one in your pageModel is going to have a model type specific to the current Page, not to the View you're directing to, and you can't change the Model within a ViewDataDictionary to a different type. MVC would complain and throw an exception.
Usage:
public IActionResult OnGet(string id) {
// check if id is good here
if (idIsNoGood) return this.View("InvalidId", new ErrorModel...);
else {
return Page();
}
}
The above will look for InvalidId.cshtml view, which can be in the same folder as your page, the root /Pages/ folder, or /Pages/Shared/. And it'll still use your Layout too, like any other page.
Just make sure your cshtml file doesn't have a #page directive at the top; this won't work for a Razor page, only a View.
Example InvalidId.cshtml:
#model MyProject.Models.ErrorModel
<h1>Invalid Request</h1>
<p>#Model.Message</p>
I have overwritten the data view for a custom graph in an extension, which returns the correct data without issue, both by re-declaring the view, and using the delegate object techniques. The issue is that when I do, the AllowSelect/AllowDelete modifications on the view in the primary graph stop working, once I comment out the overwrite, the logic works as normal.
Not sure what I'm missing, but any thoughts would be appreciated
Edit: To clarify, on the main graph, without the extension, the data retrieval and Allow... work without issue
public class FTTicketEntry : PXGraph<FTTicketEntry, UsrFTHeader>
{
public PXSelect<UsrFTHeader> FTHeader;
public PXSelect<UsrFTGridLabor, Where<UsrFTGridLabor.ticketNbr, Equal<Current<UsrFTHeader.ticketNbr>>>> FTGridLabor;
And with the extension, the data is returned correctly from the modified view, but the Allow... do not work from the main graph, only when entered on the extension
public class FTTicketEntryExtension : PXGraphExtension<FTTicketEntry>
{
public PXSelect<UsrFTGridLabor, Where<UsrFTGridLabor.ticketNbr, Equal<Current<UsrFTHeader.ticketNbr>>, And<UsrFTGridLabor.projectID, Equal<Current<UsrFTHeader.projectID>>, And<UsrFTGridLabor.taskID, Equal<Current<UsrFTHeader.taskID>>>>>> FTGridLabor;
I have also tried the other process on the extension with the same results, the data is filtered correctly, but the Allow... commands fail.
public PXSelect<UsrFTGridLabor, Where<UsrFTGridLabor.ticketNbr, Equal<Current<UsrFTHeader.ticketNbr>>>> FTGridLabor;
public virtual IEnumerable fTGridLabor()
{
foreach (PXResult<UsrFTGridLabor> record in Base.FTGridLabor.Select())
{
UsrFTGridLabor p = (UsrFTGridLabor)record;
if (p.ProjectID == Base.FTHeader.Current.ProjectID && p.TaskID == Base.FTHeader.Current.TaskID)
{
yield return record;
}
}
}
My main concern with not wanting to use PXSelectReadOnly, is that there is a status field on the header which drives when certain combinations of the conditions are required and are called on the rowselected events, sometimes all and sometimes none, and the main issue is that I obviously don't want to have to replicate all of the UI logic into the extension, when overwriting the view was the main intent of the extension for the screen.
Appreciate the assistance, and hopefully you see something I'm overlooking or have missed
Thanks
Every BLC instance stores all actual data views and actions within 2 collections: Views and Actions. Whenever, you customize a data view or an action with a BLC extension, the original data view / action gets replaced in the appropriate collection by your custom object declared within the extension class. After the original data view or action was removed from the appropriate collection, it's quite obvious that any change made to the original object will not make any effect, since the original object is not used by the BLC anymore.
The easiest way to access actual object from either of these 2 collections would be as follows: Views["FTGridLabor"].Allow... = value;
Alternatively, you might operate with AllowInsert, AllowUpdate and AllowDelete properties on the cache level: FTGridLabor.Cache.Allow... = value;
By changing AllowXXX properties on the cache level, you completely eliminate the need for setting AllowXXX on the data view, since PXCache.AllowXXX properties have higher priority when compared to identical properties on the data view level:
public class PXView
{
...
protected bool _AllowUpdate = true;
public bool AllowUpdate
{
get
{
if (_AllowUpdate && !IsReadOnly)
{
return Cache.AllowUpdate;
}
return false;
}
set
{
_AllowUpdate = value;
}
}
...
}
With all that said, to resolve your issue with UI Logic not applying to modified view, please consider one of the following options:
Set AllowXXX property values in both the original BLC and its extensions via the object obtained from the Views collection:
Views["FTGridLabor"].Allow... = value;
operate with AllowXXX property values on the cache level: FTGridLabor.Cache.Allow... = value;
First check if your DataView should/should not be a variant of PXSelectReadonly.
Without more information my advice would be to set the Allow properties in Initialize method of your extension:
public override void Initialize()
{
// This is similar to PXSelectReadonly
DataView.AllowDelete = false;
DataView.AllowInsert = false;
DataView.AllowUpdate = false;
}
Suppose I want to pass one object (reference) through several pages. I can navigate and pass parameters via Frame.Navigate(typeof(FirstPage), object). But how to pass the reference back on back press properly?
protected override void OnNavigatedTo(NavigationEventArgs e) {
if (e.Parameter is SomeClass) {
this.someObject = (SomeClass)e.Parameter;
}
else {
this.someObject = new SomeClass();
}
SystemNavigationManager.GetForCurrentView().AppViewBackButtonVisibility = AppViewBackButtonVisibility.Visible;
SystemNavigationManager.GetForCurrentView().BackRequested += OnHardwareButtonsBackPressed;
base.OnNavigatedTo(e);
}
private void OnHardwareButtonsBackPressed(object sender, BackRequestedEventArgs e) {
// This is the missing line!
Frame.Navigate(typeof(FirstPage), this.someObject);
}
But when I press back button it goes back to the FirstPage OnNavigatedTo with no parameter, and then back to the SecondPage OnHardwareButtonsBackPressed and then back to FirstPage OnNavigatedTo with filled parameter.
Could you please advice me some better approach?
In your back handler, don't navigate forwards again, just call GoBack -- and it's typically easier if you handle that at a global level rather than at a page level.
You can store your application state (the things you want to persist across page navigations) in global / static objects, or you could directly modify the object that was passed from the initial navigation (if the calling page still has a reference, it will be able to see the changes).
I would consider doing a search for "MVVM Windows Apps" and looking at some of the results to learn about a common way of building XAML apps.
I have a question regarding P2P with flex.
When passing data between two applications using P2P. I get the following error:
warning: unable to bind to property 'piece' on class 'Object' (class is not an IEventDispatcher)
I've spent a few days using Google to try and find a solution, but a can't get rid of that error. I've tried using ObjectUtils, direct assignment, and creating a new ArrayCollection WITH the ObjectUtils inside the parenthesis and still can't solve the problem.
Purpose of code:
-> Two users connect via P2P
-> 1st user can manipulate pictures (stored as objects in the array collection).
-> 1st user sends updated ArrayCollection (with changed pictures) to 2nd user
-> 2nd user's ArrayCollection gets updated and now sees manipulated pics
As far as my knowledge of Flex goes (fairly new to it), I properly Binded what needed to be binded. Using pop-ups and trace, I was able to see that the data from the ArrayCollection gets copied in properly, but it just doesn't want to display.
Here are some snippets of my code:
[Bindable]
public var taken:ArrayCollection = new ArrayCollection ([
new picLayout(1,'sky.png'),
new picLayout(2,'bird.png')
])
public function receiveSomeData(pass:ArrayCollection):void
{
// Want to replace current version of variable "taken" with
// the one passed in using P2P
this.taken= new ArrayCollection(pass.source);
}
public function sendSomeData(free:ArrayCollection):void
{
sendStream.send("receiveSomeData",free);
}
<s:Button click="sendSomeData(taken)" label="Update" />
Thank You for your help and time!
I figured out what the problem was and how to fix it - with partial thanks to these pages:
Unable to Bind warning: class is not an IEventDispatcher
Flex Warning: Unable to bind to property 'foo' on class 'Object' (class is not an IEventDispatcher)
I knew that the information was being successfully sent to the other peer, but the problem was that the objects INSIDE the ArrayCollection weren't made bindable.
My solution to the problem was as follows:
Create a loop that sends each object in the ArrayCollection along with an index that tells you what value in the ArrayCollection you are streaming.
Now, since you are "streaming" the data, overwrite the current ArrayCollection, using the setItemAt() function with first field as "new ObjectProxy(passedObject)" and the second field as the passedIndex (Note): the ObjectProxy() function forces the passed object to be bindable.
Here is an updated snippet of my code:
[Bindable]
public var takenPics:ArrayCollection = new ArrayCollection ([
new picLayout(1,'sky.png'),
new picLayout(2,'bird.png')
])
private function sendSomeData(data:Object, index:int):void
{
sendStream.send("receiveSomeData",data,index);
}
private function receiveSomeData(passedPic:Object,ix:int):void
{
// ObjectProxy needed to force a bindable object
takenPics.setItemAt(new ObjectProxy(passedPic),ix);
}
public function sendPictures():void
{
// ix < 2 because size of ArrayCollection is 2
for (var ix:int = 0; ix<2; ix++)
sendSomeData(takenPics[ix],ix);
}
