Earlier today, I installed Matisse4MyEclipsea (on MyEclipse’s invitation prompt to do so). I now get the following exception on starting Eclipse. (Using Version: 6.0.0 M1, Build id: 20070629-6.0.0-M1)

I don’t plan on using Matisse any time soon, so this is probably no major concern, but if anyone has a pret-a-porter solution, I’d love to hear about it!

(I’ll include configuration or plug-in details on request.)

Update: I disabled Matisse4MyEclipse, but I still get those error messages. (It doesn’t prevent me from working: I just minimize the error window and carry on…)

But the full story is that I did install a few other updates as well as SpringIDE. Maybe M4ME isn’t the culprit after all (I jumped to conclusions too soon).

Should I start disabling the features one after the other until I stop getting the error messages? Or is there a more painless way of getting to the bottom of this? I’ll take any advice I can get!

[pierdeux]

In the end, I did go about disabling the features one by one. The culprit seems to have been:

Spring IDE (required) 2.0.0.v200706271108

It seems there was a conflict in keybinding:

Ctrl+Shift+G => References in Workspace
Ctrl+Shift+G => Spring Beans References Search

I’ll put the question to the folks at Spring, but if someone here has some suggestions, I would love to try them (because I was looking forward to using the Spring IDE plugin!)

The original NullPointerException and the keybinding problem seem to be two different (unrelated) questions.

NullPointerException question has been asked by another user: https://www.genuitec.com/forums/topic/nullpointerexception-in-xmlmultipageeditorpart/

The keybinding problem came from my installing SpringIDE on top of MyEclipse, without first disabling the proper MyEclipse features, as pointed out in here: https://www.genuitec.com/forums/topic/springide-2-0-integration/

Thanks to Christian on the Spring Forums for pointing me in the right direction!
