Hello,
I'm dealing with a quite challenging problem right now:
We're developing an application consisting of multiple GMF-generated
editors. They have a shared data model and one of them serves as interface
editor. It is used to specify an interface consisting of several node types.
Now some other editors use this interface. This means, they include the
interface's nodes in one of their diagrams. The interface nodes should only
be altered by the interface editor. The problem now is: When an interface is
changed, how can the diagrams (respectively the diagram files) using it be
updated? (the interface changes must be propagated to all diagrams using
it). The affected diagram's editor should not be opened! Is there an easy/
elegant way to do this? I'm clueless so far...
Thanks in advance for your help!
Regards,
Johannes

Thanks for your replies. First of all, I don't think that a shared
editing domain, as Jan Koehnlein proposed, makes sense here. As far as I
understand it, the shared editing domain is used to simultaneously
update multiple views, but this doesn't apply here. My Editors won't be
open at the same time.
What I rather want to have is the possibility to say: A model "X" made
with editor "Y" should use an interface made with the interface editor.
The saved interface consists of two files "name.interface" and
"name.interface_diagram".
Now i want the interface domain model data stored in "name.interface" to
be loaded into model "X".
According to your post, Alex, I assume you know how this works. Can you
please tell me about this?
The topic of this thread sounds a bit misleading, because I started
solving my problem using a different (bad) approach. It should rather be
something like "loading domain model data stored by editor A with editor B".
Thank you in advance!
best regards,
Johannes

Hello Alex!
Thank you very much for your answer. This was exactly what I needed. Linking
elements from different diagrams works also very well. The only problem left
now is, that I want to automatically create shortcuts upon opening a
diagram. This works, but my shortcuts are multiplied on each diagram
opening. Is there a way to check, which shortcuts already exist in my
diagram? where are the shortcuts stored?
Best regards,
Johannes

Hello Alex!
Thank you very much for you helpful answer (again :))
I still have a problem however, a strange one:
I have two diagrams A and B (of different types/ metamodels). B contains
shortcuts to A. When I delete some of the original elements in diagram
A, the visible representation of the shortcuts in B gets completely
messed up. A has two nodetypes, represented by black and white squares.
After deletion of some nodes in A, it happens, that the shortcuts in B
change the color from white to black. Links can be drawn to white
shortcut-nodes. After changing the color, this doesn't work anymore and
existing links disappear.
I also have this problem, when enabling shortcuts from A-diagram type to
itself and it happens too, if the shortcuts were created manually using
the popup menu.
I found two functions, that seem to handle the shortcut updating:
refreshSemantic() in [editorName]CanonicalEditPolicy and
refreshSemanticChildren inherited from the CanonicalEditPolicy
superclass. However, the code of the latter one isn't available.
Do you (or someone else) have an idea, what is causing this?
Thank you in advance!
Best regards,
Johannes
