Hello

I have a GMF/EMF project that is working just fine, with exception of one layout aspect. I have a containment element that accept a kind of nodes, and when a pick one of that nodes and put inside that containment in the containment appears two nodes. But theres only one there.

Probably these doesn't make sense without an example.
I've uploaded three images, the first one is my project without the containment. In the second image a add the containment, and in the third image I put the node inside the containment (and it duplicate the node).

Does anyone know what is causing this?

Another problem I'm having, is in the gmftool I define the nodes description, and it doesn't appear in project new instance.

How about the data model before and after you put the Goal into the compartment? Are there two nodes or only one?

Only one. And if I open the xml file generated, even with the compartment specified there is only one goal inside that same compartment. It seams to be a visual problem.

Then you must wait for some experts to answer, I am new to GMF but I asked so that you could give more details to the question. Sorry about that.

Thank you anyway.

This problem is kind of weird, because like I said, the xml is correct, only the visual editor is multiplying the number of nodes in a containment.

Hi Patricia,

i'm having the same problems. Imho this is a Bug in GMF. I created a sample project to demonstrate the problem.

The domain model is a simplified version of UML2 Package Diagrams as shown in the figure below

index.php/fa/6284/0/

The diagram canvas is mapped to "Model", nodes representing packages and classifiers are mapped to the respective domain model elements.

The bug can be reproduced as follows: Create a new package diagram. Insert a package and a class as top level nodes. Save the diagram. Then drag and drop the class into the package. The resulting domain model is correct. Unfortunately the notational model contains two nodes referencing the same domain model element.

Is there something wrong with my gmfmap file? Or is this really a bug in GMF itself?

EDIT: Is it related to this bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=237059 ?

Hi,

I've reproduced this with the simplePackage example above. All intermediate models seem to be fine so this appears to be a GMF bug as previously suggested.

Cheers,
Dimitris

I did not follow your issue, but in general, in the GMF project, it is
better opening a bug in doubt rather than not opening one.
I don't think any GMF contributor will blame you for opening a bug that
is not one. Just be precise in your report.

Unfortunately, it seems that no one cares about this bug... 3 months after filing it, it is still assigned to the project inbox Sad
