Hi,
I've been experiencing some behaviour in my GMF editor that I don't
understand. When I load an instance of the editor (i.e. by doubling clicking
on a *.my_diagram file), I receive a stack trace, such as the one shown at
the bottom of this post, in the editor view.
However, if I close and re-open Eclipse with the editor view still open, the
editor loads without error, and I can edit my model.
Having investigated the problem somewhat, it's apparent that when I receive
an error, GMF is loading a dynamically-typed version of my model (i.e. all
of the EMF objects are instances of DynamicEObjectImpl). When the editor
works as I intend, the EMF objects loaded are instances of the meta-classes
generated by my model (i.e. instance of things like BlockImpl).
Does anyone know why my model is being loaded "dynamically" when a new
editor is instantiated? How do I work around this?
Apologies if my explanation is a little unclear! Thanks in advance.
Cheers,
Louis Rose.

Louis,
EMF typically finds your model because
EPackage.Registry.INSTANCE.getEPackage(<your-model's-nsURI>) will return
the EPackage for your model given the namespace URI that it finds in the
document being parsed. Is there some reason why this registry might
disappear or might not be present in the first place? Have a look at
your model's plugin.xml and be sure the generated_package extension
point is registering your model with the same nsURI value as appears in
the generated XyzPackage.eNS_URI.

Hi Ed,
Many thanks for the reply.
I see! You were absolutely correct - there was a reason why the registry
might not be present. Another suite of plug-ins that I use do some magic
with the registry, which was causing the conflict with my GMF editor.
Removing the reference to my model from that suite of plug-ins solved the
problem.
Thanks very much for your insight.
Cheers,
Louis.
