Hi All,

I created two EMF metamodels "a.ecore" and "b.ecore" and combine them using "Load resource" -> "a.ecore" to "b.ecore". Then I created class "MyClassA" in model "a.ecore" and classes "MyClassB" and "SubB" in model "b.ecore". Class "MyClassB" have containment references to classes "MyClassA" and "SubB". At the same time, class "MyClassA" hane non-containment reference to class "SubB". Here is my EMF metamodels:


After, I created "test.model" in exceed with "MyClassB" as root and instances of "SubB" and "MyClassA" as children. Here is my model:


When I try to insert in reference field of class "MyClassA" instance of class "SubB" nothing happens. Model just don't see "SubB" when I do this:


How to insert instance of the "SubB" in "MyClassA"?

Hello Nikolay,

One general point, this is Epsilon forum, maybe it is better you ask your question in EMF forum?

I am not sure, but the following can be the case. Since your subB instance is in a containment reference, you may not be allowed refer to it. BUT, this should not be the case.

Also, the picture for selection does not look like as if it is from a non-containment reference. Usually, you set such a reference using the Properties view.

Hello Nikolay,

I agree with Burga that it seems a containment problem. But without the complete meta model (i.e. to see the containment properties) its hard to tell.

Also agree with Burga, that this is purely an EMF problem and someone in that forum might help you faster.
