Hi,
Without any diagnostic information, I can only guess that the reason is
that your listener extension is registered against a different
editing-domain ID than the one that your editor is using.
What does your plugin.xml look like? Which registered editing domain is
your editor using? Are there any warnings/errors in the log regarding
unknown editing domain IDs in your listener registration? What kind of
NotificationFilter does your listener define?
HTH,

I checked that everything was fine (I guess). Here is a sample of my
plugin.xml:
<extension
point="org.eclipse.emf.transaction.editingDomains">
<editingDomain
factory="fr.mopcom.modal.tools.ModaltEditingDomainFactory"
id="fr.mopcom.modal.tools.editingDomain">
</editingDomain>
</extension>
<extension
point="org.eclipse.emf.transaction.listeners">
<listener
class="fr.mopcom.modal.tools.listeners.ModalResourceSetListener ">
<editingDomain
id="fr.mopcom.modal.tools.editingDomain">
</editingDomain></listener>
</extension>
Here is a sample of code modifying the CommandStack:
Command cmd = new RecordingCommand(editingDomain, "Add Element"){
@Override
protected void doExecute() {
PackageableElement element = (PackageableElement)
factory.create(metaClass);
element.setName(name);
pack.getOwnedElement().add(element);
try {
pack.eResource().save(editingDomain.getResourceSet().getLoad Options());
} catch (IOException e) {
e.printStackTrace();
}
}
};
try {
cmdStack.execute(cmd, Collections.EMPTY_MAP);
} catch (InterruptedException e) {
e.printStackTrace();
} catch (RollbackException e) {
cmdStack.undo();
}
and finally the handleNotification of my listener:
@Override
protected void handleNotification(TransactionalEditingDomain domain,
Notification notification) {
System.out.println("notification occured");
}
I can't see what's wrong here.
thx.

Hi,
The only piece missing from the snippets that you quoted is how you are
getting the editing domain from which you get the command stack to
execute the command. Are you retrieving it from the
TransactionalEditingDomain.Registry.INSTANCE using the same ID as the
extension XML?
As an aside, I see that you are saving a resource using the resource
set's default load options. Many load options don't pertain to the save
operation. Just pass an empty map (Collections.EMPTY_MAP) to get the
resource set's default save options.
Cheers,
Christian
