DIFFERENT TYPES OF RELATIONSHIPS (CONNECTIONS) [message #227092]

Hi all, I'm a begginner in GMF.

I have the next simple structure in my ecore to model classes &
relationships among them:

MyDomain:
|
|-- classes: MyClassType
|-- relations: MyRelationType

MyClass->MyClassType
|
|-- subTypes --> MyClasstType
|-- supertypes --> MyClassType

MyRelation-->MyRelationType
|-- classes --> MyClassType

I'd like to have a diagram in which I can draw classes, and
relationships among them as usually but besides I need to draw the
supertypes and subtypes of a class as other type of relationship and I
can't do it using only gmfmap with the above ecore. The problem is that
it only lets me use MyRelation.classes as Source/Target feature but what
I want is MyClass.subtypes and MyClass.supertypes to be a new connection
over the canvas using ,of course, another tool from the palette and
another figure from gmfgraph.

Is it possible without writting custom code in the EditParts classes or
without changing my model structure?

All answers will be happyly received. Thanks a lot to everyone who can
give me a tip/clue to solve this.

Hello Juan Miguel Ávila Nieto,

Your situation looks similar to the Ecore diagram, EClassESuperTypes link.
Try checking this example and compare .gmfmap used there with your one.
