dialog, + problem in storing window instance in context

Posted on Dec 03, 2007 at 04:11 PM 9 Views

Hello Friends,

I am trying to implement a dialog as defiend in PDF doc ( Dialog Boxes in Web Dynpro Applications ) http://209.85.129.104/search?q=cache:fA--oXHmRTEJ:https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/42af9f90-0201-0010-6099-ba67e5426bdfdialogsboxeinwebdynproapplications&hl=en&ct=clnk&cd=1

In this document, he mentioned how to store the instance of the dialog window in context in order to destroy later on:

wdContext.currentPopupElement().setWindowInstance(window);

( I have also created the value node popup and its value attribue WindowInstance of type IWDWindow , but when I use this line of code, i.e wdContext.currentPopupElement().setWindowInstance(window);, I got null pointer exception,

if I comment this line, I can open the window dialog, ( which atleast make me confirm that my window obj is not null ) dont know why I am getting this exception ...

Any idea....

Regards,

    Now instead of this:

    wdContext.currentPopupElement().setWindowInstance(window);

    I used this.

    wdContext.createPopupElement().setWindowInstance(window);

    I did not get the null pointer exception on this line, however when i try to retrieve the instance like this:

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

    Got null pointer exception ?

    any idea why I am getting null pointer exception ?

      Correct, and

      3. As the popup is closed from an action handler of another view (e.g a view inside the popup containing a "Close" button), the context attribute must be created in a common controller (component or custom controller) and mapped from the view that openes the popup and from the view that contains the close-action.
