Hello,
I have a problem with displaying a "inherited" class in a compartment. I
place it properly but it just won't display.
Let's say I have those classes in my model :
Nature:
- trees: Tree (container reference)
Tree:
-name
-apples: Apple (container reference)
-specialApples: SplecialApple (container reference)
Apple:
-color
SpecialApple
-specialAttribute
The class SpecialApple "extends" the class Apple.
In my gmfmap I have a TopNodeReference to with a NodeMapping to a Tree.
This NodeMapping has ChildReferences to "Apple" and "SpecialApple" . It also
has a Compartment Mapping with Children set to Apple and SpecialApple.
So my problem is when I run the diagram, I can place and Apple to the
Compartment. I can also place the SpecialApple but when I release the mouse
button, it just doesn't show in the diagram. If I open the xmi file of the
model instance, I can see the SpecialApple.
When I remove the inheritance between the Apple and SpecialApple, it works
ok !!
Any ideas ?
Thanks a lot,
Tex;

hi Tex,
its a bug in the ???VisualIDRegistry within the method getNodeVisualID().
the problem is that types are listed from general to specialized.
so the first matching (super)type in the hierarchy is returned instead
of the most specialized type.
if allready commited a bug report
https://bugs.eclipse.org/bugs/show_bug.cgi?id=195272
a simple workaround is just to change the order of 'if' operations with
the types ordered from specialized to general.
