[news.eclipse.modeling.gmt.amw] Re: WeavingModelManager and EditingDomai

[Marcos Didonet Del Fabro <mddfabro@xxxxxxx>]

Hello,

the editing domain is a facility used by the UI for creating model 
elements, deleting them, the undo actions, etc.

To be able to use the current code, you need to have an editing domain, 
because it is used to get the resource set in the 
"WeaverModelManager.getWeavingModelRS".

You may modify this method to get the resource sets in a different way, 
for example, by creating a new one using ResourceSetImpl(). However, in 
this case you cannot directly use some facility methods from the utility 
classes.


Regards,

Marcos.
