List bug snippet

The problem is when the List component is placed on the invisible composite. Here is the example when it is placed on an inactive TabItem. The dialog will not response and can not be closed after been opened.
The Firebug write to console the following:
org.eclipse.swt.widgets.List: Element must be created previously!

The snippet is attached.

i too have this problem in a rather complex application (a framework actually). we have a text input field, which displays a drop-down list to provide completion proposals (you know the trick ;)). when i try to use that field with RAP, i get the "org.eclipse.swt.widgets.List: Element must be created previously!" message in firebug.

i have no idea how to tackle the problem... any hints?

Could you please apply this patch to the 1.3 maintenance branch? Otherwise a JS error is thrown if the conditions described above are true. Thanks, Stefan.

+1. I think it's safe to apply this patch to the SR.
