Comment 2 Tomas Pavek 2001-07-16 17:27:03 UTC 
So which component causes the exception?
Comment 3 Marian Mirilovic 2001-07-17 15:14:08 UTC 
JSplitPane with JInternalFrame I think.

If you add to JFrame JInternalFrame and after add JSplitPane you
obtain NPE. 
If you try add JInternalFrame and other component - exception isn't
rised.
If you try add JSplitPane and other component - exception isn't rised.

It's independent from Layout.

This not happens if you add first JSplitPane and second
JInternalFrame, but if you now change layout or select JInternalFrame
in ComponentInspector you obtain the same exception.
Comment 4 Marian Mirilovic 2001-08-13 08:52:46 UTC 
The same behaviour in [pilsen](010810), this is reason for change
version to FFJ3.0 ea.
Comment 5 Marian Mirilovic 2001-08-21 15:20:47 UTC 
This cause JSplitPane, if you add JSplitPane to JScrollPane you obtain
NPE(attachment2 [details]) again.

NPE 2, JSplitPane to JScrollPane
Comment 7 Tomas Pavek 2001-11-01 16:48:03 UTC 
I cannot reproduce the second problem - with JScrollPane - in current 
dev builds. The case with JInternalFrame has been fixed.

MetaComponentCreator.java rev. 1.14
