getting resource from model element [message #1070070]

Hi,

I am opening a EMF model with a generated editor.
When I am selecting (by clicking) an element of this model, I would like to know which resource it comes from.

Using eContainer(), I can go up to the DocumentRoot but I have seen that when closing and opening back the editor, the DocumentRoot object's id changes so I cannot rely on this object to know which resource I am working on (I have a table mapping resources to DocumentRoot s).

So I'd like to get the resource's URI, which should not change, but I don't know how to get it from the model element.

Can someone give me a track ?

Thanks

From any EObject x (it doesn't have to be a root object) you can use
x.eResource() to get its containing resource and of course from that you
can get the URI.
