Hello again ;)
what I try to do is simple. To model the different states of a class I
want to add a StateMachine as a child to a Class. I tried it like this:
StateMachine machine = UMLFactory.eINSTANCE.createStateMachine();
Class stateFullClass = getClassFromPackage(classDiagram,
stateFullClassName);
stateFullClass.allOwnedElements().add(machine);
"getClassFromPackage" searches in a Package "classDiagram" for a Class
"stateFullClassName". This method works fine. But an
UnsupportedOperationException is thrown when .add(machine) is called. So
how can I add a StateMachine to a Class?
greets
J.R.

Jan,
The list of owned elements is a derived union, hence read-only. Try
something like this instead:
StateMachine machine = (StateMachine)
stateFullClass.createOwnedBehavior("Machine",
UMLPackage.Literals.STATE_MACHINE);

Hi Jan,
The easiest way would probably be from the class, simply call
Class#createOwnedBehavior( .. ); A StateMachine is a Behavior.
The reason why adding to the allOwnedElements() did not work is because you
were trying to add an element to a derived collection.
Regards,
