hey folks,
this is basically the same problem I noticed in some GMF Tutorials.
Example:
I made an Ecore model in Eclipse 3.2 using the shipped graphical ecore
editor (GEE). Afterwards I opened the same metamodel (*.ecore_diagram)
in the GEE from eclipse 3.3M-something, draw a new association and
realized that it shows the multiplicity of the edge. So far so good.
Here's the problem:
it just shows the multiplicity for the new associations, not for the old
ones. (in this case I can simply create a new ecore_diagram and
rearrange everything)
I guess the reason is the same like following example I noticed from the
GMF Tutorials:
I created a mini-Domain Specific Modeling (DSM) tool with a container.
When I tested it, I created a diagram with a Container C1. Happy, I
added a compartment to the Container class to take Actions. Again, I've
re-build my editor, opened the same file as before and tried to add
actions to C1 ... impossible. Quite a while later I realized that when I
add another container C2 it accepts my actions (because I created C2
with my new Editor). Can someone explain to me what's going on there,
and how I can incrementally build a graphical editor without forcing the
"customers" to throw there old models away each "release"?
P.S. If I open the new ecore_diagram in the old 3.2 GEE, instead of the
correct association I find a label "Invalid View- remove from Diagram".
Thanks so far
stefan
