[news.eclipse.modeling.gmf] list of popupPredefinedItem id's - where?

[markitus <jxtamarc@xxxxxxxxx>]

Hi there, 

I'd like to know the id for every single action that can be added or 
removed to a contextual menu. I'm trying in vane to disable some of them, 
I don't know where to look to know the id for each given action. I want 
to enable/disable each different action depending on a element from my 
diagram, that's why I'm trying to find the id for every 
popupPredefinedItem.

thanks in advance.

Marc.
