En blancoHi!
I have a problem. I generated an editor from my EMF model using GMF. While
testing the editor in Eclipse, I create a new diagram using the wizard, then
I save and close it. Then I reopen the saved diagram and it's OK. But, if
I close Eclipse (with the saved diagram in the workspace) and reopen it;
when I try to open my saved diagram I get this exception:
java.lang.NullPointerException

If I create a new diagram from the wizard; and then try to open the saved
diagram it is opened correctly.
I think the wizard initialize something.
Any suggestions?
Thanks in advance.
