Popup window error

[former_member181928]

hi

I am implementing a popup window tutorial .

In my view one context node contains one attribute which is of the type IWDwindow.This attribute stores the reference of the window so that it can be destroyed.

Node - Popup

Attribute - Windowinstance

While executing the below given statement

wdContext.currentPopupElement().setWindowInstance(window)

the

"wdContext.currentPopupElement()" gives a null pointer exception..i dont know why?

Do i have to initialise it first if yes how

plese help

Hello Nilesh,

Make node Popup property cardinality and selection to 1..1 and set init leadSelection to true.

The problem is that your node doesn`t have any node elements and you are trying to call method of element with lead selection which doesn`t exist. So, you should make cardinality 1..1 or 1..N (doesn`t make sence because you don`t need to store multiple references to windows), to force dynpro runtime to create node element automatically.
