Hello,
is there an elegant way to handle exceptions thrown by the model in the
commands. Currently my commands inherit the
org.eclipse.gef.commands.Command which doesn't allow to throw excpetions
in the execute-method.
Greetings,
Alexander

Actually, it is retrieved from the getAdapter, but more correctly you would
want to install your new CommandStack in the EditDomain which you would
associate with the viewer.
