Hello:

First to all, thanks you for your help.

I need modify the visual diagram dinamically. When the user throw a link from a object to other object, I need generate other links to some others object, impacting it in the model of my metamodel. (like if the user throw this generated links manually).

Is there some way for do it using Epsilon or I need modify the source code?
In the case I need modify the source code. Is possible get some documentation about the code automatic generated?

Thanks you.

Jose Miguel.

Hi Jose Miguel,

Thanks for using Epsilon, and for the feedback!

I'm guessing that you're using EuGENia to generate the visual editor...

Do the links need to be added while the model is being changed in the visual editor? Or could they be added later, after the model has been saved?

If the links are to be added while the model is being changed with visual editor, I think the best approach is to modify the generated source code...

In the generated .diagram project, there will be some EditPart classes in the your.project.diagram.edit.parts package. If I recall correctly, the handleNotificationEvent(Notification event) method can be used to react to changes to the model. The GMF documentation might provide some tips on how best to achieve the automatic addition of links.

Cheers,
Louis.

Hi Louis!!

Yes, of course, I'm using EuGENia for generate the visual editor Wink It's really fantastic.

Adding while the model is being changed in the visual editor is the ideally, but I don't discard add this links when the model is saved if the other form is very complicated for to do.

I have checked and in the method handleNotificationEvent(Notification event) come a event when this element is created, modified or removed. I will have a look more about it. Thanks you Wink

Only one more question. In the case I want add this links when the model is saved. How can I do it? If I use EOL I will modify the model but this changes will not impact to the editor. Am I right?

Thanks you very much for your time Wink

Great. Yes, this is the approach I would use to add the links while the model is edited. The Notification object should give plenty of information about the type of event that has occurred.

I'm guessing, but I think there is a save() or a doSave() method that could be extended to run some EOL code. Propagating the changes back to the editor is tricky. Perhaps calling resolveSemanticElement() would be enough? I think this might be a question to ask on the GMF forum.
