Navigate Different Metamodels [message #1597267]

Hello everybody,

this is my first post, sorry for my english, isnt my mother language. I have been working with eclipse for a while and working with the examples and forum so far so good.

Now i have encountered a ploblem, and even if i have tried, i dont know what path to follow. I´m trying to open a new representation of a model, but from other domail class.

By the moment, i have a model representation with the domain class, the same meta model of the model. I want to create a navigation to a new diagram, of the same model, but with the domain model of other metamodel.

So far i have created the two diagrams without problem, but when i do the action that triggers the diagram change, i receive a dialog to enter diagrams name, but nothing happens.

Between the two metamodels already exists the needed connections.

Maybe is a easy question, but i have tried a lot and nothing seems to work.

Thanks in advance.

> Hello everybody,

Hi Alain,

I'm not sure to understand your needs properly. Can you provide us more
details (such as a sample project) about your scenario?

Im trying to open a model representation from an already model representaton. I have a diagram representation, and when double clicking a element i want to create a new representation programatically with that element as root. I use an external java action where i will create the new representation. I have read the documenteation and search in the forum.
This is the code i have so far:(inside de external java action. The clicked element is passed as "EObject objectInSession" )

//get session
URI myRepresentationsFileURI = URI.createPlatformResourceURI("/4_MPT_Models/representations.aird", true);
Session siriusSession = SessionManager.INSTANCE.getSession(myRepresentationsFileURI, new NullProgressMonitor());

//open representation
Collection<DRepresentation> myCollection = DialectManager.INSTANCE.getAllRepresentations(siriusSession);
for(DRepresentation a : myCollection){
if(a.getName().equals("myRepresentation")){
DialectUIManager.INSTANCE.openEditor(siriusSession, a, null);
}
}

When executing, i get the following error:
!ENTRY org.eclipse.gmf.runtime.diagram.ui 4 4 2015-02-09 16:35:12.711
