AWT-EventQueue-0" java.lang.ClassCastException


P

patrick

Ive got a swing application with quite a lot of code. With several JFrames
being created at various stages.
Its working fine but Im getting this ClassCastException sometimes at no
predictable time or place in my code.So I cant find the source of the
problem with normal debugging.

Anybody any ideas on how to find the problem here??

TIA
patrick
