Hi,

i have a ecore Model for a special Statemachine.
The State an Transition Classes look like this:
State : EClass
->name : String
->transitions : Transition

Transition:EClass
->id : String
->target : String


the target Attribute in Transition should be the name of a state.

Of course, I could change the ecore Model and add State References in the Transition Type Class but is there a way without changing the ecore Model for that?

Hi Sui,

If you set State.name as the unique ID in EMF, and Transition to an
EReference of State, you should be able to emulate this functionality
without needing to modify any GMF code.

Cheers
Jevon
