Problem with merging multiplicity-many eOpposites [message #1749158]

Hi,

I am trying to resolve a merge conflict involving a multiplicity-many eOpposite reference. I would expect this to work out-of-the-box, since it seems that this case is implemented by the default equivalence engine (DefaultEquiEngine). However, the merge does not seem to work as expected.

Here are some details.

I have two classes (A and B), referring to each other by references A.b(1) and B.a(*). These references are eOpposites and non-containment. I then create a conflicting change on A.b. After resolving the conflict on A.b, I can see that the B.a reference is not updated.

Is this a known limitation of the DefaultEquiEngine? If so, do you have any suggestions for overcoming it?

Thanks in advance!

Vlad

Hi again,

After investigating a bit more, I think the root cause of my problem goes a little further. I am executing model merging twice, and it seems that the second time there is some information missing.

I will very likely open a new forum thread for this, but as of now it looks like the DefaultEquiEngine actually works as it should.

If possible, this thread should be deleted.

Cheers,
Vlad
