Thanks for the tip, will check it out. After a week hammering at this
error, I've lost all faith in my ability to create multiple editors and
make them function together. I get this error, and Load Resources shows
nothing in "Browse workspace".
So thought I would ask you guys what needs to be done.
Here is what I do:
1. Single ecore and genmodel (with one root element for each editor)
2. Derive tooling, graph and map for each editor.
3. Derive a generator with these attributes set unique:
- File extensions
- Model ID
- Visual ID
- Plugin ID
- Editor ID
Any input is, as always, greatly appreciated :)
Best Regards,
Tomas Zijdemans

Hmm. It seems I have got things working. And I have a definitive source
of the error. Either I have misunderstood something, or there is a bug
in GMF.
As previously stated, everything works in EMF. This just occurs in GMF.
Scenario:
- A is super of B. B is super of C and D. (A and B should be abstract,
but this does not seem to effect anything)
- If root can contain A's, and an editor for C and another for D is
created - the error occurs.
- If root can contain C's and D's, and an editor for C and another for D
is created - the error does not occur.

I've done a reinstall of eclipse and gmf 2.0.1.
Created a root with two elements that relate to each other. Derive a
diagram for both. Run it, and still get the same error!!

I still haven't seen a full stack trace showing the error. You should
be able to get it from the Error log view. Have you been able to get
the debugger to stop at the point when the exception is thrown using an
exception breakpoint?

protected void doSynchronize(Object element, IProgressMonitor monitor)
throws CoreException {
ResourceSetInfo info = getResourceSetInfo(element);

for (Iterator it =
info.getResourceSet().getResources().iterator();

402 Resource nextResource = (Resource) it.next();
handleElementChanged(info, nextResource, monitor);
}
return;
}
super.doSynchronize(element, monitor);

Alex,
Making a copy of the list is a bit expensive. Depending on if you want
to visit the demand loaded resources or not, I'd suggest either
List<Resource> resources = resourceSet.getResources();
for (int i = 0; i < resources.size(); ++i)
or
List<Resource> resources = resourceSet.getResources();
for (int i = 0, size = resources.size(); i < size; ++i)
The former would visit even ones added during the traversal, while the
latter would visit only those known to be in the list at the start of
the traversal.
EcoreUtil's resolveAll is written this way because we want to resolve
proxies even in the demand loaded resources.
public static void resolveAll(ResourceSet resourceSet)
{
List<Resource> resources = resourceSet.getResources();
for (int i = 0; i < resources.size(); ++i)
{
resolveAll(resources.get(i));
}
}

Christian,
There's EcoreUtil.ContentTreeIterator.ResourcesIterator, but that's used
for the tree iterators. The iterator for ResourceSet.getResources
itself is just a plain old fail fast iterator. I'm not sure it's a good
idea to make it be not fail fast given that some clients might well
expect to see only resources that were there at the start of the
iteration, which is generally a safe assumption when using an iterator.

Hi, Ed,
Thanks for clarifying! I'm glad I'm not out to lunch.
I see that the tree iterator naturally has different semantics from the
usual iterator. The very process of iterating contents may add to the
resources list (resolving containment proxies) so this is necessary in that
context. That isn't the case with simple iteration over
ResourceSet::getResources(), so I withdraw my remark.
