Hi,
I'm using a GMF Editor to display a part of my model, but when the user
clicks a particular node, I'd like more complexity to be revealed in an
XTextEditor type view, allowing the user fine-grained control. My question
is:
How do I go from the selected node in GMF, to loading it in the XText
view? I gather there is some addressing mechanism I should look at for
this? Any help would be appreciated.
Thanks!
Maurice

I think Jan will publish the example as soon as he finds the time.

It is a very specific problem. I'm afraid there is not much
documentation available for navigating to an EObject that has been
instantiated by an Xtext parser.

Sounds reasonable.

The GMF editor simply visualizes the contents of the resource which has
been created by an xtext parser. This objects are refered to as semantic
objects. They are linked to the AST via an EAdapter. That's basically
the structure that the parser produces.
