Hi,

Is this in the context of a GMF editor?

Cheers,
Dimitris

Hello Dimitrios!

Yes, It is.

I would like validate when a object or link is created, similar like now I can validate when the model is saved, but when a object or link is created.

Thanks you very much. Wink

Hi,

My - wild - guess is that you'll either have to modify the create
commands in the GMF editor or attach a listener to the resource so that
you get notified when it changes (e.g. something is added/removed) and
then call ValidateAction.runValidation(...) - but I must admit I haven't
done anything like this. Have you perhaps tried asking in the GMF newsgroup?

Cheers,
Dimitrid

Hi Dimitrios:

I have tried call ValidateAction.runValidation(...) in the method doExecuteWithResult of my XXXCreateComand, XXXReorientedComand etc. but I don't know How can I get the View Object.
I'll ask in the GMF newsgroup.

Thanks you very much for you help Dimitrios.

GMF supports validating the model, so the question is how to trigger it.
A fairly generic solution is listening to changes to the command stack,
and then trigger the validation (that I think normally happens when you
save). Then you know that the command has completed, any model listeners
have reacted to model changes etc.

I think you can get hold of the command stack through the editing
domain. The EMF editor uses this technique to set the dirty flag of the
editor, so it should be fairly easy to find example code.
