Eike,

Congrats, everything, I mean everything is working well.

However, I have a problem I can't find. I think you have my ecore file
to reference...

When I go to create and add a new ServiceGroup object in one client I
get an error in all other clients that follows.

!ENTRY org.eclipse.ui.workbench 4 2 2007-11-13 12:46:27.381
!MESSAGE Problems occurred when invoking code from plug-in:
"org.eclipse.ui.workbench".

....

These other clients are refreshing a tree view for the Facility model
object. In the course of calling get modelChildren the following is
called...which seems to cause the error above.
getFacility().getEchostar(). Echostar is the root object which I am
using for some other purpose. If you look at the model Facility contains
NamedEquipmentList.

I don't see anything in my code that looks suspect.

Thanks,
Mark.
