[news.eclipse.modeling.gmf] Anyone used Multiple Editors on one model ?

["Alan" <awm_abu@xxxxxxxxx>]

Hello all,

I am wondering if anyone has any experience of a situation where they have a 
model which can be edited by mutiple GMF editors at once ?
In our case we have a model in which we can build hierarchies of objects.
So I create Object A and Object B in a diagram. Then I choose to compose the 
two and so I create Container A. If I double click Container A in the 
diagram I open a new diagram which shows Object A and B.
Changes to the inside of a container can effect it.
For example Object A could have an interface which it exposes upwards so 
that Container A also shows it.
In this case I have changes in one editor affecting changes in another. 
(remove the interface from Object A which means it has to go from Container 
A)

We are running into quite complex issues with :
Undo and redo - one stack per editor or per model and so across mutiple 
editors ?
Conflicting changes being made across editors ?


Any help appreciated

thanks,
