Problems using our own Meta-Model [message #1041661]

Hello everybody,
we have the following problem:
We want to add an eObject to our own Meta-Model with the following method:

laresModel.getBehDefs().add(newBehaviorDefinition);

This is working so far, but when we link it to the graphical representation in the Addfeature with the link method:

link(containerShape, addedDomainObject);

Then this additional line in the CreateFeature is necessary:

getDiagram().eResource().getContents().add(newBehaviorDefinition);

Otherwise the graphical representation is linked with null.
But this additional line causes our eObject (newBehaviorDefinition) to be removed from the laresModel.getBehDefs(), which is a part of our own Meta-Model.
Is there any way to keep the eObject in our own model and to link it to the graphical representation?
With best regards,
Alexander, Mario and Dominik

Alexander,

did you see this older forum entry?
http://www.eclipse.org/forums/index.php?t=msg&th=172247&start=0&S=acb08c1bf425f0ccb0106fb3a46a4bad

It deals with separating diagram and domain data into different resources.
Both resources would be loaded into the same reosurce set/editing doamin
inside your editor.

Hi,

@Andreas: Never thought of that we´re having two models in use...
Can I replace the model of the tutorial with ours anyhow? Or is
it necessary to use both?

Thanks,
Mario

We used the following to create an instance of our model (laresModel is the very top):

public void setRoot(LaresModel laresModel) {
	ResourceSet resSet = new ResourceSetImpl();
	Resource resource = resSet.createResource(URI.createURI("bla.xmi"));
	resource.getContents().add(laresModel);
	this.laresModel = laresModel;
}

This method is defined in an independent Singleton-Class in the project.

At a quick glance, you are creating a dedicated ResourceSet for your laresModel. For cross-referencing to work, your resource should be created in the resourceSet of the Grpahiti Diagram. EMF only can cross ref models in the same resource set.

Added laresModel to the e-resource of the diagram. Now the link-method is working fine with "newBehaviorDefinition" in laresModel!
Now I have to check out if this works with more than one diagram - using the drilldown-feature - as well.

Thanks a lot!!!
