[news.eclipse.platform.rcp] Re: is there a preferred RCP mechanism for u

["CL [dnoyeb] Gilbert" <Lamont_Gilbert@xxxxxxxxxxxxxxxxx>]

Question is not related to RCP.  When the model changes you don't get 
ResourceChangeEvents.  You get those when the resource changes.  That 
is, when the file is renamed or moved, but not when its altered while open.

You need to register a listener to your model.  Your model needs to fire 
events when it makes significant changes.  Typically the edit part 
registers to listen to the model withn its 'activated' and deregisters 
when its 'deactivated' I believe.
