Ecore Diagram Editor - how to have split diagram files [message #1015252]

I've got a .ecorediag (and corresponding .ecore file autogenerated by diagram editor) that has quite a few common EClass's that I use in multiple projects. I've been coping the same .ecorediag from one project to the next in the spirit of getting the new project done fast.

What I'd like to do is have a common.ecorediag and common.ecore file that has my base (common) EClass's in it. Then have a project specific model.ecorediag and model.ecore that contains project specific EClass's which includes referencing EClass's in common.ecore[diag]. For example, common.ecore[diag] might contain an Address EClass and a project's model.ecore[diag] might contain an EClass called Astronaut which has an ERef to Address from common.ecore[diag].

I still want to be able to use Diagram Editor to edit both common.ecorediag and a project specific model.ecorediag.

Can I do this? If so, how? I can't seem to find anything in Diagram Editor that would let me reference another diagram.

Mike,

You can use Load Resource... in the outline of the diagram editor (much
like you can in the Sample Ecore editor, to load other Ecore models
which you can then reference in that diagram and by models displayed in
that diagram.

Ed,

Thanks for the pointer.

I found "Load Resource..." by clicking on the background of my project .ecorediag and then loaded the common.ecorediag. Or was I suppose to load common.ecore? I tried both. I don't see any visual difference. Am I suppose to see any visual differences?

In my project.ecorediag editor I created a new EAttribute and tried to set the EType in the popup menu to an EType from common.ecore[diag] but it was not listed.

I also tried to create an EReference in project.ecorediag to an EType in common.ecore[diag] but again nothing from common.ecore[diag] was in the popup menu for EType's.

If there is some kind of doc/tutorial on this I'd be happy to get pointed at such. Smile

Thanks again.

I'm not sure that helps. Does it appear in the outline?

Yes.

It should appear in the outline and in general you can drag things from
the outline onto the canvas.

I've never tried loading another diagram but in general diagrams don't
reference other diagrams they only reference other Ecore models.

Such things are in short supply...
