EMF EditingDomain in GEF Editor [message #553141]

Hi,

I'm using EMF and GEF to visualize and edit a model.

The EMF.Editor provides the standard tree editor and the GEF editor is in use to have a graphical view on the same model and to edit it, e.g. with the palette.

The goal is to use the both editors independently , therefore both can access the file which includes the model data.

If both editors may be open, they are supposed to register as a listener to the CommandStack included by the EditDomain(GEF) or EditingDomain(EMF) of the other editor, so changes made in one editor are transmitted to the other one and replicate the command on the CommandStack there. (Undo and redo should be realized this way.)

One problem I focus now is to write the changes made in the GEF Editor to the data model without using the EMF.Editor, so it has not be opened.

Is there a possibility to add an EMF EditingDomain (to access the underlying model) in the GEF Editor and synchronize it with the one in EMF Editor, if this will be opened?

Can I use a TransactionalEditingDomain for both editors to administrate the model? Of course I would use a extra EditDomain for graphical editing in the GEF Editor.

Thanking you in anticipation

Wouldn't a single integrated editor be better?

It sounds more like you should have a shared editing domain. That issue
is discussed in the context of GMF quite frequently...

You've looked at the red book about EMF/GEF intergration?

The red book talks about how to integrate the two command frameorks;
GEF's is a modified version of the originally shared EMF one. :-(

That's what GMF does yes.
