Unhandled event loop exception [message #815099]

Hi,

I'm converting few eclipse plugins to use eclipse version 3.7.2 (those has use eclipse version 3.4.1 before) and I'm having some problems with adapters. My plugin has it own navigator which uses tree model and it is used to open correct editors to elements. With 3.4.1 eclipse everything worked well, but now I'm having some NPE:s when I open context menu on the top of some item in navigator.

Is there something changed in newer eclipse versions with adapters, or what could cause this problem? I have debuged creation of adapters to elements and everything seems to work normally. I would really appreciate any help that somebody could give to me. Smile

Man, you need to look in all the eclipse plugins' classes that your plugin is using, compare the two versions, and edit where it needs.
As simple as that, and last but not least, enjoy coding!
