Comment 2 Jan Horvath 2007-04-20 08:31:54 UTC 
can you please add information about java ee version?
Comment 3 Radim Roska 2007-04-20 08:55:48 UTC 
exception occurs in both supported version of EE ( Java ee 5 , j2ee 1.4 )
Comment 4 Radim Roska 2007-04-20 09:22:19 UTC 
im sorry i didnt mentioned that exception occurs only in nb installed by
installer with all packs. Daily builds work fine.
Comment 5 Petr Blaha 2007-04-20 09:51:39 UTC 
This is serous issue for J1 preview since we will use new installer where users
can choose predefined configuration and they will install more packs on their
machines. We should find which pack causes this exception.
Comment 6 Radim Roska 2007-04-20 10:07:48 UTC 
i have reproduced this on nb installed just with web pack ( even without GF
server installed )..

Precisely all i've installed was base IDE, Java IDE and Web Pack...
Comment 7 Martin Adamek 2007-04-23 15:26:46 UTC 
I wasn't able to reproduce it, but here's the possible fix. Please try to
reproduce again with that.

Andrei, can you please review the patch?
Comment 11 Andrei Badea 2007-04-24 09:58:10 UTC 
Patch looks fine to me. 

Perhaps "addPropertyChangeListener was called by the superclass constructor,
that is, before the pcs field was initialized" is slightly clearer than the
proposed description.

Changing to P1 as duplicate P1 was reported and it seems to be quite important.
