Exception opening models with Papyrus editor [message #817844] Sat, 10 March 2012 14:03 Go to next message
Eclipse UserFriend
Dear all,

I have a few papyrus class diagrams in a particular project on which I have been experimenting Acceleo. Today, without any apparent reason, I am unable to open any of the papyrus models, neither the .di, nor the .uml files. On the former I get the exception reproduced below. All these models where created with Papyrus and some of them are a few months old, there hasn't been any change that could have corrupted the model.

This is happening on Helios; is there anything else I can do to further describe the issue?

Thank you.

org.eclipse.papyrus.resource.ModelMultiException: Problems encountered while loading one of the models.
----- exceptions : ----------
org.eclipse.papyrus.resource.uml.UmlModel : The class 'EModelElement' is not a valid classifier
org.eclipse.papyrus.resource.notation.NotationModel : The class 'EModelElement' is not a valid classifier

First of all apologies for the belated follow up, but finding one's threads can be a daunting task in this forum. I haven't solved this issue, just installed Indigo and can now work with the old models.

Meanwhile, on Indigo, Eclipse started freezing every time I try to switch to the Papyrus perspective.

Thank you for the help.

Hi,


In Papyrus 0.10, this should not happen anymore (When you open the model with the Papyrus editor). However, if you are using a different tool, such errors may still happen on some specific models.

Can you please give more information about what you're doing?


Regards,
Camille

I use Topcased 5.3.1 (the last release at this time)

and ... MDT Papyrus 0.8.2.v201305290825.

Maybe I may upgrade Papyrus with mitigating the regression risk ?

Hi Didier,

As far as I know, Topcased is not compatible with Papyrus 0.10.X (Nor 0.9.X)
