Description Jan Skarvall

2010-11-17 08:10:14 EST

I have been working with a fairly complex class diagram for a while with some struggle but without any problems.
A similar problem occurred when I tried to initialize a component diagram from the UML model, but I could still edit my class diagram. But now, after having quit Eclipse and started it again, the class diagram cannot be opened anymore but gives the error below.

What steps will reproduce the problem? I really don't know. Sorry.

I'm still on Galileo due to I am relying on a plugin that does not work on Helios yet.

Best regards
Jan Skarvall
