I generated a new GMF project using an existing set of .ecore, .gmftool,
..gmfgraph and .gmfmap files (BTW: this all used to work in a previous
version of GMF, but - burned by experience with GMF - I restarted from
scratch just migrating these mentioned files). These files describe a
very simple model that has "artifacts" and "processes" and connections
between them (processes can read and write artifacts/files, that's about
it). The graphical representations are rectangles and ovals and - of
course - lines/arrows for the connections. The entire thing is just a
toy example to get up and running with GMF.
I generated the .genmodel and created the model's source and the .edit
and .editor projects. Next I created the diagram editor .gmfgen file
from its three .gmf* input files and from that the .diagram project.
Everything compiles fine. So far, so good.
When I start these newly created plugins in a runtime workbench I can
create a new project and a new diagram with it (and the palette etc. all
look fine), but when I try to create any graphical object by selecting
the corresponding create tool and then clicking somewhere on the canvas,
absolutely nothing happens.
Instead, for each click on the canvas there is an exception on the
console:

--------------------------------------------
If I check the LeonardoDiagramImpl.java file listed on top of the
stacktrace it reads:
--------------------------------------------
....
public EList<Artifact> getArtifacts()
{
// TODO: implement this method to return the 'Artifacts' containment
reference list
// Ensure that you remove @generated or mark it @generated NOT
// The list is expected to implement
org.eclipse.emf.ecore.util.InternalEList and
org.eclipse.emf.ecore.EStructuralFeature.Setting
// so it's likely that an appropriate subclass of
org.eclipse.emf.ecore.util.EcoreEList should be used.
throw new UnsupportedOperationException();
}
....
--------------------------------------------
In fact, in that file ALL methods are empty and throw
UnsupportedOperationException-s.
What's going on here? Isn't GMF supposed to generate all that code???
What am I missing here?
This is on Europa (base eclipse as well as GMF and all it's prereq's).
As I said: this example used to work with a previous GMF version (some
2.0 milestone, but I forgot, which one) using the exact same steps as
described above.

Hi Michael,
Actually, it's EMF, not GMF who is responsible for generation of this
part. Anyway, I believe this gets generated if the feature is declared
to be derived transient or volatile or something like that.
Best regards,
Boris

That's right, if a feature is set to be volatile, then no variables are
allocated and all the accessor methods need to be implemented by hand.

I first went through all .ecore elements and their attributes in the
..ecore model editor and couldn't find anything "volatile" nor
"transient". In the end I threw the .ecore file into my favorite text
editor and fair enough, there were four "eStructuralFeatures" that had
attributes '... volatile="true" transient="true"...', namely all the
node types that I had defined and the diagram root element.
So, no wonder: if this controls the code generation then I understand
that nothing was created. But how these attributes came into being or
rather, why and how and by whom they were ever set to true is beyond
me...
So, I'm apparently a little bit further now with my toy example, but for
some reason the connections aren't properly created. Some are, some are
not... I guess, you can expect another append soon.
