Display popup inside applyResult method of ovs?

Question

Hi,
I have implemented an object value selector for a field.
Now what I want to do is to display a popup window when   the user selects a row inside ovs popup (ie. inside the applyResult method).
The popup window (with ok and cancel buttons) is being displayed, but when I try to destroy it inside the event handler for a popup ok or cancel buttons, the exception gets thrown. The exception says something about No item found on the list??
I guess it has something to do with trying to display it inside applyresult method?
The details:
Popup is being displayed inside applyResult method of a customController (MaterialIndexCust)
     IWDWindowInfo windowInfo = wdComponentAPI.getComponentInfo().findInWindows("ConfirmExpandSpecWindow");
     IWDWindow window = wdComponentAPI.getWindowManager().createModalWindow(windowInfo);
     window.setWindowPosition(WDWindowPos.CENTER);
     window.setTitle("Question");
     wdContext.currentPopupElement().setWindowInstance(window);
     window.show();
Here's the code from the event handler which is from the same custom controller :
        IWDWindow window = wdContext.currentPopupElement().getWindowInstance();
        window.destroyInstance();
The actual event had to be defined in another controller.
I've tried these things with IWDConfirmationDialog as well  as my custom dialog.
Any help is appreciated.
Regards,
Ladislav
