I have debugged an error, and it seems like this line in setName()
crashes, when I call setName from the getname method.
eNotify(new ENotificationImpl(this, Notification.SET,
EditorPackage.CLASS_NODE__NAME, oldName, name));
Why would a notification crash? (it's parameters - oldName and name are
correct and valid)
Regards,
Tomas

I made a try catch, which resultet in:
java.lang.IllegalStateException: Cannot modify resource set without a
write transaction

you should create a command and execute it on through the commandStack.
If you want to make it undoable by eclipse you want to use
AbstractEMFCommand.
This might help you as an example, it applies a profile to a package:
private static class ApplyProfile extends AbstractEMFOperation{
Package package_;
Profile profile;
public ApplyProfile(TransactionalEditingDomain editingDomain,
org.eclipse.uml2.uml.Package package_,Profile profile) {
super(editingDomain, "ApplyProfile "+profile.getName());
this.package_=package_;
this.profile=profile;
}
@Override
protected IStatus doExecute(IProgressMonitor monitor,
IAdaptable info) throws ExecutionException {
try{
package_.applyProfile(profile);
return org.eclipse.core.runtime.Status.OK_STATUS;
} catch (Exception e){
return org.eclipse.core.runtime.Status.CANCEL_STATUS;
}
}
}
And is executed by:
// Ausfuehren
AbstractEMFOperation op = new
ApplyProfile((TransactionalEditingDomain) editingDomain,model,oioProfile);
try {
UMLDiagramEditorPlugin.getInstance().getWorkbench().getOpera tionSupport().getOperationHistory().execute(op,
new NullProgressMonitor(), null);
} catch (ExecutionException e) {
UMLDiagramEditorPlugin.getInstance().logError("www.OiO.de Profile
Application Error" , e);
}
For background information, read the EMF-Transaction Tutorials
Working with EMF Operations and Creating Transactions.
You can find both in the Eclipse Help.

I'll try this out. I thought of using a GMF command like:
SetRequest setRequest = new SetRequest(nodeElement,
nodeElement.eClass().getEStructuralFeature(EditorPackage.CLA SS_NODE__NAME),
a.getName());
selectedElement.getDiagramEditDomain().getDiagramCommandStac k().execute(
new ICommandProxy(new SetValueCommand(setRequest)));
But your solution sounds much better.
Thanks again :)

What exactly do you mean by this, how can I make that distinction?

Thanks, but I really just need a simple command that sets a name to an
element.
I've tried to get this working with:
TransactionalEditingDomain domain = TransactionUtil.getEditingDomain(book);
CommandStack stack = domain.getCommandStack();
// execute some change
Command cmd = domain.createCommand(SetCommand.class, new
CommandParameter(book, EditorPackage.BOOK__NAME, "dummy"));
stack.execute(cmd);
But I think I'm getting the editing domain wrong, any suggestions?
Thanks,
Tomas
