One editor for multiple ecore models [message #988575]

Hi, I have a question about multiple ecores.
Is it possible for an editor to represent elements from multiple ecore models?
I have to make an editor that uses a ecore which maps elements from two other ecores. A sample of the mapping ecore is on the picture.
index.php/fa/12559/0/

My intention is to use shortcuts to make elements from the other two ecores appear on the canvas and then relate them to each other.

My main problem so far is that while I am able to load more than one ecore to my gmfmap file, I cannot create the generator because I can only set one ecore on the creation wizard.
Is it possible what I am trying to do or it is not supported by GMF?

Thank you very much
Spiros

Spiros,

I'm not sure the right answer, but isn't it possible to create a gmfmap
file for each of the models and generate the infrastructure for each of
them? Doesn't the third "combining" model then reuse the generated GMF
things from the other two models?

Well in my case I have already the other editors for logical and deployment. So what you say is right. When I drag something from another model, it uses the notation that I have made for the element in the other editors.
My problem is that the mapping editor(image) needs to know what to store for example in the attribute pc of the PCtoProcessMap. So that means that I need to map my shortcut(from the deployment and logical) to the mapping model.
I read that to do this I need a fake node in the mapping gmfgraph to map the shortcut to it. But I cannot use more than one ecores in the gmfmap to do that.
So I do not know how to make the elements from the 2 other models, interact with elements from the mapping model in the mapping editor.

I hope I made my situation more clear and I did not confuse you more Smile

Thanks!

Hi,

did you try to right-click in the gmfmap editor and select "Load Resource ...". This should load a second ecore model into the gmfmap editor.

Hope that helps!

Ralph

Hi Ralph,
well I do not have a problem of loading the other ecores in the gmfmap file. I do the Load Resource and find them in my workspace.
But on the next step, when I have to generate the gmfgen file, the wizard allows me to set only one ecore and so it complains about the elements that belong to other editors.
Any ideas on that?
Thanks
Spiros
