Hi all,
i got an exception but can't explain, why it's thrown. What i'm doing is,
creating a tabpane and add it into a
splitpane. In the tabpane there is a treetable. The splitpane is part of an
ULCFrame. The tabpane is created completely.
It works fine at least but now it won't. I'm certain of making no serious
changes to the code. Just some issues to
localization. Can't comprehend where the NPE is raised...
Thanks for your help and best reagards,
Carsten.
