Hi all,
in my LifecycleManager I've created a new IPreferenceStore object. This
I've put into current context:
context.set(IPreferenceStore.class, defaultValuesNode);
(context was previously injected into LifecycleManager with @Inject
private IEclipseContext context;).
Now if I inject the IPreferenceStore in a MPart:
@Inject
@Preference(value="/instance/com.acme.work")
private IPreferenceStore preferences;
the preferences field is null (even if I omit the value attribute). On
the other hand, if I call
EclipseContextFactory.getServiceContext(Activator.getContext()).get(IPreferenceStore.class);
all preferences are available, which means that I've chosen the wrong
context (Activator delivers the bundle context for "com.acme.work"). But
how can I say which context for injection is to use?
TIA,
Ralf.

Ok, I forget to mention that I've used the
com.opcoach.e4.preferences.ScopedPreferenceStore from
https://github.com/opcoach/e4Preferences.
