Endless event loop for dialog window causes stack oveflow

[Former Member]

The wdFireEvent* call in the controller keeps firing itself and causes a stack overflow from the endless loop. I see in debug that the dialog is only calling the fire event once when the close button in clicked. Also put a breakpoint in the handler on the view that launches the dialog but the handler code never gets touched.

I have:

- controller event DialogClickedEvent

- view method handleDialogClickEvent() as:

Event Source: <the controller name>

Subscribed Event: DialogClickedEvent <the controller name>

The window instance is being saved after window.open() but since the handler code never gets called it doesn't get a chance to get the instance ID and destroy it.

Anyone ever see this happen?

The event is fired from a popup dialog in the main view.

In main view:

The dialog is created when an error is displayed in a UI MessageArea

IWDWindowInfo windowInfo = wdComponentAPI.getComponentInfo().findInWindows("IPSList");

IWDWindow window = wdComponentAPI.getWindowManager().createWindow(windowInfo, true);

window.setWindowPosition(300, 150);

window.setTitle("Multiple Sales Org for PRESALES");

window.open();

wdContext.currentSalesAreaPopupElement().setWindowInstance(window);

event handler (Event Source = TimeEntryComp , Subscribed Event = ChooseAreaEvent)

IWDWindow window = wdContext.currentSalesAreaPopupElement().getWindowInstance();

window.destroy();

In dialog: (user selects either Update or Cancel button -> both end up firing same event)

Button click OnAction:

wdThis.wdGetTimeEntryCompController().fireChooseAreaEvent();

In controller:

event: ChooseAreaEvent

method:

public void fireChooseAreaEvent( )

{

//@@begin fireChooseAreaEvent()

wdThis.fireChooseAreaEvent();

//@@end

}

I was originally just going to use IWDConfirmationDialog but got the missing button bug with MessageManager.

Mike,

The code looks fine to me. have you redeployed and tested the application?

Hi,

Try modifying the code like this especially the last bit:

public void fireChooseAreaEvent( )
{
//@@begin fireChooseAreaEvent()
wdThis.wdFireEventChooseArea();
//@@end
}

That was it - looks like I left out the "wd".

Thanks!

Hi Mike,

Please explain me when you fire this event ?.

You have created the event, probably you might have created a method which fires this event. when and where do you call this event ?

You also need to understand that when you fire this event , your view should be alive in the assembly. Then only your view can catch this event and hadle it.
