Associations with same name don't appear in Schema composer

[Geert Bellekens]

When a class has two associations with the same association name, only one of them will show up in the schema composer.


Steps to Reproduce:
- Create class A, B and C
- Add an association from A to B with name "test"
- Add an association from A to C with name "test"
- Create a new schema composer schema
- drag class A into the schema
- notice that only one (random) association with name "test" will show up with no warning at all.
- remove the names from the associations
- notice that now both associations are visible in the schema composer

That's 'cos they're the same relationship!   (only kidding!  )  But the behaviour you describe is merely a defect.

The determination of semantic equivalence is non-trivial (as we discovered when we wrote our consolidator) - it's not rocket science, but it is not straightforward.
