Hi!
I'm trying to refresh domain model (I get domain data from external corba
source) from a thread (every few minutes) and I get NullPointerException
from:
PlatformUI.getWorkbench().getActiveWorkbenchWindow();
but if I run it from action (pressing button on gui) everything is ok.
I'm using AbstractTransactionalCommand to manipulate domain model and I
need TransactionalEditingDomain.
I do it like this:
TransactionalEditingDomain editingDomain =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().getActiveEditor().getDiagramEditPart().getEditingDo main();
AbstractTransactionalCommand command = new
AbstractTransactionalCommand(editingDomain, "Changing domain model", null);
then I execute command and if I do it from gui everything is ok, but if
the above code is called from thread it does not work.
Any suggestions, am I doing something wrong?
Thanks in advance,
Igor Novak

Hi Igor,
I suggest you use Display.getDefault().syncExec() to run your code.
Cheers,
Dimitrios
