Where does RAP store instance-scope preferences? [message #521747]

Hello everybody,

I'm looking for a place where instance-scoped preferences are stored by rap.

Actually I want to track instance-scoped preferences. So if a preference
value gets changed - the event listener is invoked.

String myPluginId = "..."
IEclipsePreferences ep = sc.getNode(p);
ep.addPreferenceChangeListener(prefListener);

However this code seems not to be working. If I change values on
preference pages - the listener doesn't get invoked.

If you follow IPreferencePageContainer#getPreferenceStore(), you will
probably find the implementation

what is "sc"?, where does "p" come from?
