Description Konrad Windszus

2011-04-20 05:53:06 EDT

The change http://git.eclipse.org/c/m2e/m2e-core.git/commit/org.eclipse.m2e.core.ui/src/org/eclipse/m2e/core/ui/internal/M2EUIPluginActivator.java?id=c95b8b38c146025e2a4f20982e679326ee6c8ca2 broke the access to the preference store. Therefore some dialogs cannot open and also the POM editor.
The log says:

This is caused by using InstanceScope.INSTANCE which is not a valid constant in Eclipse 3.6 and earlier. It is named InstanceScope.SCOPE there.

Ah, sorry about that, I reverted it.  The bundle versions differing from the Eclipse release version tricked me.
