One of my customers wanted to view my Cayenne 1.1 model as an ER Diagram under windows, so I upgraded the model using Cayenne modeler 3.0, then 3.1B2, all under linux.
I then emailed them the simplified model and told them to view it using Cayenne 3.1B2 (under windows). They get this error when they open the model. I also installed Cayenne 3.1B2-win and got the same error under Windows 7. Looks like it's related to perferences -- I'm not sure if it has anything to do with this particular model.
