Hello all,
I have an EMF model with an element defined like this:
Class Section
leader : 0-1 reference to Leader (another class)
assistants: 0-M reference to Assistant (another class)
Of course, I have a containing "model root" class to hold multiple Sections.
When I run my model, it works as I'd expect - I can only create one leader
but I can create many assistants. I can only drag a leader in if there
isn't one already, but I can drag multiple assistants in - no problem.
Now, in GMF I've defined my mapping as follows:
Section
Compartment LeaderCompartment
Leader
Compartment AssistantsCompartment
Assistants
Seems to work fine at first - I get a Section rectangle with two
compartments, one for the leader and one for the assistants - I can create
only one leader but many assistants, and I can't drag the Leader tool to the
Assistants compartment or vice-versa. I can also drag leaders or assistants
from one Section to another. But here's where it goes wrong - for some
reason, it's allowing me to drag and assistant from one Section to the
Leader compartment in another. When I drop, it displays the assistant in
both the Leader and Assistant compartments. It's also allowing me to drag a
leader in one Section to another Section that already has a leader, and
displays two of them.
Both of these actions violate the underlying EMF model - niether action gets
persisted in the EMF model, and when I close and reopen the GMF model, the
labels for the incorrect entries get changed to what appears to be some
values from within the gmfgen model. As far as I know, I have the mapping
set up correctly - it seems to honor the object types and cardinality when I
use the create tools - it's just in drag & drop from one figure to another.
I'm running GMF version 1.0.0.v20060627-1200 if that helps.
Thanks for any info!

I feel it's the same as https://bugs.eclipse.org/bugs/show_bug.cgi?id=151975
