Hi,

I have followed the tutorial in the following link to create GMF editor

"www.devx.com/architect/Article/43366/1954"

Iam facing following error. I have 3 objects in my Palette - Application,Entity,Relation.

1. Drag 2 entities onto the editor
2. Try to make relation from source entity to target entity.
3. Result is Target entity is removed from editor and no connection is shown

Thanks for your help

Sarath

Found the solution..Relation object in my palette is connection represented by Entity related to other Entity.....
So Entity should have reference to Entity....In the ecore file i have specified this reference as containment(true). This is the cause of problem...After resetting it everything worked fine.
