Hi all,
I'm not sure whether this is an EMF or a GMF problem, so I'll post to both
NGs. I can't really recall what caused the trouble, but when loading a file
into my GMF generated editor, I get tons of messages like
!ENTRY org.eclipse.gmf.runtime.diagram.ui.resources.editor 4 1 2007-02-07 11:09:04.989
!MESSAGE Unresolved reference 'DATE_ARRIVAL'. (platform:filename, 33, 189)
The reference in question always points from an element that is displayed in
the GMF editor to an element not part of the GMF models.
How can I find the source of this message? It doesn't seem to be related to
the UnresolvedReferenceException (tried to catch it with the debugger - no
luck). I haven't found the message text in the GMF components either...
Thanks
Volker

Okay, I'm getting closer - and though it appears to be a problem of GMF
origin, I suppose I need some EMF help here.
From what I can see, the GMFResource I need to get the GMF-based editor
working doesn't care about the IDs specified by the ecore model, but uses
strings like "_lQ0LurapEdu-JpXuZtvRxg". This is why
xmlResource.getEObject("DATE_ARRIVAL") fails, although the attribute
containing this value is marked as "iD".
Question: Is there any way (example, documentation, ...?) on how to create a
resource set (resource, editing domain, ??) that can be used for both EMF and
GMF operations?

Volker,
I'm not sure why this posting didn't show up in both newsgroups.
I think this is likely produced by
org.eclipse.emf.ecore.xmi.UnresolvedReferenceException and
represents an IDREF (a same document reference) to something that
can't be resolved.
Based on your latest comment I would ask if you are using the resource
implementation generated (if there is one) and registered for your
model? It sounds like you are using a resource that specifies to use
UUIDs and that isn't what you want. So using just a plain old
XMIResourceFactoryImpl is likely what you want...

Volker,
A resource implementation will be generated and registered only if the
generator knows that special options are needed. If there is no such
need, the default XMIResourceFactoryImpl would be used. I don't think
GMF requires you to use GMFResourceFactory so you should register
XMIResourceFactoryImpl to handle your file extension. This can be done
using the editing domain's resource set's resource factory registry.

I have to admit that I didn't really care about the resource implementation
until I ran into problems. The EMF editor (method createModel) retrieves a
resource from the editingDomain, and I didn't care what implementation was
behind it. However, for the GMF integration I need a
TransactionalEditingDomain that can be wrapped into a FileEditorInputProxy
object, and this EditingDomain provides a GMFResource. This resource
implementation in turn seems to use UUIDs as you mentioned.
BTW, if my descriptions sound like a blind man prodding and poking around,
that pretty much reflects what I'm doing here ;-)

That plus reading the TransactionalEditingDomain's header comment gave me tha
(okay, one of the) essential hints: I had to cleanup the GMF generated plugin
manifest because the registration performed there caused the GMFResource to be
pulled in. Thanks a lot! I'll try to find something to hit my head with, then
approach the next set of troubles...
