[news.eclipse.modeling.mdt.uml2.uml] Component, Port and Interface

[Christian Hein <hein.@xxxxxxxxxxxxxxxx>]

Hi all,

I have the following code:


UML2Factory umlfactory = UML2Factory.eINSTANCE;

Component component = umlfactory.createComponent();
component.setName("ProviderComponent");
		
Interface interf = umlfactory.createInterface();	 
interf.setName("HelloWorld");
		
Port port = umlfactory.createPort();
port.setName("Source");

But in the following line I get an UnsupportedOperationException
port.getProvideds().add(interf);

I wonder if somebody can answer how to add this interface to the list of 
provided interfaces of the port.

Thanks in advance
Christian
