Yes,qwerty I configured it that way (as an object stereotype in my TB as Eve recently recommended me), but then...how can I access attributes of the metaclass and, even better, values of theses attributes that have been defined so far?
For example:
for: Committee.name='Steering committee'
being able to get: Committee instance.name =
:Steering committeeby selecting in a listbox among all existing names
instead of simply getting :
:Committee InstanceIn metamodel, what should be the relation type between Committee stereotype that extend Actor metaclass and Committee Instance stereotype that extend Object metaclass to make Committee element attributes, TV accessible to Committee Instance element ?
