Hello,
I have two Metamodels: Core and Entity (Entity knows Core). Core defines
something like ModelElement and Dependency. In the Editor I created a
LinkMapping to have Dependencies between entity::Entity and
entity::EntityConstants. Of cource, the the normal behavior is that one
can create Dependencies between all ModelElements and this is not what I
want. I want to restrict the Dependency creation to Entity ->
EntityConstants.
I tried to define link constraints like:
self.oclIsKindOf(EntityConstants)
self.oclIsKindOf(Entity)
This fails because Entity/EntityConstants seem to be unknown:
Invalid expression body 'self.oclIsKindOf(Entity)
'. Cause: Invalid expression body 'self.oclIsKindOf(Entity)
'. Cause: ERROR in (variableExpCS): (Unrecognized variable: (Entity))
Can anyone give me hint how to proceed.
Cheers,
Mathias

Hi Mathias,
Use both type names as qualified, the way Alex has suggested.
As you use two metamodels, it is unclear which package was taken
as the default one for resolving un-qualified names.
If you have tried so already, could you please post a simple test models
that we could reproduce this?

Hi Varun,
It is not easy to see what erros you report here,
as you use 'ocliskindof' instead of 'oclIsKindOf'.
Also, 'Actor' used as type first and then as a package
in 'Actor::DiagramElement' indicates there might be other
causes of errors.
