Hi all,

Just a quick question if I may:

Has anyone ever found when using EuGENia that after modifying your
original emfatic model and then going through the phases of gmf code
generation, the resulting diagram editor behaves not as expected? I've
been making small changes to my emfatic file and have found that sometimes
the resulting editor doesn't let me add elements to the diagram.

Other common peculiarities are that if I close the new eclipse instance
(to play with the new editor) then reopen it, the diagram editor magically
works for a short time. Then it will break, e.g., if I resize a box (e.g.,
for a state chart), it won't change shape, but will cause a modification
to the diagram file (indicated by the '*' that prefixes the file name in
the tab that contains the diagram). Then upon reopening the editor I get:
"Could not open the editor: The feature 'name' is not a valid feature",
with the following error trace:

============ BEGIN >>>
java.lang.IllegalArgumentException: The feature 'name' is not a valid
feature

<<< END ============

I should point out that my emfatic file makes use of another file via the
"imports statement", and that I've modified the createContents() method of
one of the <CLASSNAME>EditPart.java files in the my.diagram.edit.parts
package.

Also, I'm not sure whether anyone knows where might be the likely place
for the error I have: GMF or Epsilon... I'm not sure.

PS. Note that the editor was working fine until this morning when I
decided to make some little changes to my original emfatic file, which
promptly led to funny behaviour in the editor, and I was just trying to
understand why.

Best,

Edd
