Comment 8 kate 2008-02-29 13:46:06 UTC 
Description:
===========

1] New JFrame
2] Add new JMenuBar to JFrame
3] Add new JPanel (jPanel1) to JFrame
4] Add new JPanel (jPanel2) to JFrame
5] Inspector Window: JFrame -> Set Layout -> Null Layout
6] In Designer Window move jPanel1 over JMenuBar as displayed in screenshot b.jpg

This results in java.lang.AssertionError regularly but I think that the previous exception (NullPointer) is just only
another consequence of the same problem.
Comment 9 Jana Maleckova 2008-03-03 08:01:21 UTC 
I followed the description you wrote there and I encountered AssertionError. I will enclose it there as well.
Thanks for reproducible steps.

Comment 11 Jan Stola 2008-03-03 15:10:14 UTC 
This issue has nothing to do with JMenuBar. It is sufficient to use the following steps:

1. Add two JPanels into JFrame with Free Design.
2. Change layout manager to null layout.
3. Move one panel into the other.
   => exception is thrown
Comment 12 Tomas Pavek 2008-03-25 10:49:15 UTC
