[gmf-dev] How to display all figures?

[Thomas Gaus <thomas.gaus@xxxxxxxxxxx>]

Dear Team,


Sorry put i have to ask again :) Is it possible to have different figues for a ecore class? The following diagrams should help to mention the problem.

My ecore diagramm looks like:



Now i want to create an editor that has a figure for "Element1" and "Element2".
I expect the following result:



But in reality i've got:



But the XML file in the background contains both elments.Although i've tried a lot of things it's not possible to display the element two.
I can only create the elements which are placed in the first place in the genmap definition.
Why?

I got following stack trace:

I hope you can help me. I tried to explain the problem with this easy example. In reality it's a problem of a complex editor.
I've validated all my components in each step.



i've attached the source. Please don't forget to remove ".txt" to get the zip file :).


(See attached file: model.zip.txt)
