Comment 2 Tomas Pavek 2003-11-18 18:33:16 UTC 
Looks like some problem with BeanInfos, needs to be checked if not bug
in jdk.
Comment 3 Milan Kubec 2003-11-25 10:48:14 UTC 
This exception is also thrown when selecting BoxLayout or
GridBagLayout for some component. I will attach ide.log, since the
stack trace is a bit different. Marking as P2 because it makes form
editor unusable.

Tomas, please, could you check it. It seems that this issues is not
the only one with the same problem (BeanInfo). Thanks.
Comment 6 Tomas Pavek 2003-11-28 14:23:33 UTC 
Okay, installed jdk1.5.0 b29 and did some investigation. Looks like
bug in jdk - Introspector fails on beans having no properties (which
is the case of BoxLayout in the case of ColorPicker; and also
GridBagLayout). Bug 4960996 was submitted. No workaround is possible.
Comment 7 Tomas Pavek 2003-12-02 09:38:52 UTC 
Should be fixed in tiger build 30.
Comment 8 Milan Kubec 2003-12-04 13:05:48 UTC 
Verified, fixed in JDK 1.5.0 b30.
