Re: [mdr-users] MDR and Swing

Hi Martin,

Thanks for your reply. Yes, the application freezes forever. I have 
looked into it and managed to get somehow deeper into the problem. I 
believe it has to do with threads and it is not limited to Swing only.

For example when I populate a RefPackage (e.g. refPackage) in the main 
method of my (Swing) program and try to access it on a button click 
event - AbstractAction.perform() -, since the perform() function is run 
by the dispatcher in a different thread, I get no response (the code 
freezes at the statement I try to access e.g. refPackage.refAllClasses() 
and the statement does not return!). However, if I populate refPackage 
inside the perform() method (so that it is in the same thread with the 
accessing code), everything works fine. Any ideas?

Cheers,
Dimitrios
