Hi,

I did a diagram editor using the sub-diagramming to reopen itself some
times. I noticed that when I use that feature (I open a diagram from a
diagram) and then I close everything, If I re-open my diagram then I get
many NPE's. Here is a stacktrace :

java.lang.NullPointerException

I'm using Europa fall and the corresponding GMF on Linux.

Any hint or advice ?

Hello Cédric,

Can you see the same problem with GF-generated Ecore diagram example (it
is possible to double-click) on ePackage to open subdiagram of the same type.

Hi Alex,

Using the ecore editor for a few minutes, opening/closing packages and
subpackages I get the same stacktrace.

Hi Cédric!

I also have editors which apply diagram partitioning.
But I don't get any NPEs when opening and closing windows
like crazy.

Do you have added some elements to the toolbar?
I haven't.

Could you post the link to your bugreport in this thread
as well. I am eager to know if there is a problem which
could also become mine.

Cheers,
Nicolai
