Greetings,
(Before posting this question, I did search for an existing bug in the bug database, but I didn't find anything)
I'm trying to fix a bug in my Xtext 2-based editor. When changing preferences for a particular project, the changes get saved to all the projects in the workspace.
After some debugging, I think the problem is in PreferenceStoreAccessImpl, in the method getWritablePreferenceStore(Object), line 59:
public IPreferenceStore getWritablePreferenceStore(Object context) {
lazyInitialize();
if (context instanceof IFileEditorInput) {
context = ((IFileEditorInput) context).getFile().getProject();
}
if (context instanceof IProject) {
ProjectScope projectScope = new ProjectScope((IProject) context);
ScopedPreferenceStore result = new ScopedPreferenceStore(projectScope, getQualifier());
result.setSearchContexts(new IScopeContext[] {
projectScope,
new InstanceScope(),
new ConfigurationScope()
});
}
return getWritablePreferenceStore();
}
when the context is a IProject, this method creates a ScopedPreferenceStore using the passed IProject as one of the scopes. I think the problem is, the created ScopedPreferenceStore is never returned, instead, this method always returns the one from getWritablePreferenceStore().
I'm so sorry that at this point I can't confirm this bug (by actually changing Xtext's code and running my project again.) Does anybody know if this is a known bug?
Many thanks in advance,
-Alex

Hi Alex,
this is not a know bug. Please file a ticket. Thanks.
Workaround: Bind your own subtype of PreferenceStoreAccessImpl for your
language.
Regards,
Sebastian
