Accessing editor preference page preferences from Edit plugin [message #516976]

I have a RCP EMF project and there is a bunch of functionality in the edit plugin that requires access to the user-defined preferences of a custom editor preference page (from the Editor Plugin). The way I have implemented this is as follows.

When the EditorPlugin initializes the editing domain, it passes its IPreferenceStore to the edit plugin.

The Edit plugin has a class that defines the preference page preferences and default values using the IPreferenceStore passed by the EditorPlugin. The Editor plugin has a custom preference page that uses this class to populate it.

The Edit plugin has a bunch of classes with code that makes reference to the current values of the preference store preferences.

I had to add org.eclipse.ui as a plugin dependency to the Edit plugin in order to make IPreferenceStore visible.

Everything works fine when I run from the IDE but when I build the application and run it standalone I get the following stack trace:

Could not open the editor...
java.lang.NoClassDefFoundError: org/eclipse/jface/preference/IPreferenceStore
at aaf.datagen.preferences.AAFPreferences.initialize(AAFPrefere nces.java:135) <-- Part of the Edit Plugin
at aaf.datagen.presentation.DatagenEditor.initializeEditingDoma in(DatagenEditor.java:543)
at aaf.datagen.presentation.DatagenEditor.<init>(DatagenEditor.java:493)
at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Nativ e Method)
...

AAFPreferences.java:135 = preferenceStore.setDefault( AW_INSTALL_LOCATION, AW_INSTALL_LOCATION_DEFAULT );

Can anyone explain why I'm getting this error? Is there a better way to achieve what I'm trying to do? One that works?!

Thanks.

Greg,

IPreferenceStore is located in org.eclipse.jface so I think you should
narrow your dependency to that. Perhaps you've not deployed all the
dependencies you need?
