Implement an interface that is exposed by a component in a class inside the component and show it in the corresponding class model

Question

I have a Component in a component diagram that provides several interfaces. Now i'd like a class in a class diagram that describes this component to implement this interface.

What i tried:

• Drag the interface into the class model --> results in the message 'When dropping embedded elements to a diagram, you must drop them on theit correct owner.'
• Creating the interface in the class model, then trying to link it with the interface in the component model --> I didn't find a way to accomplish that.
• Adding the class to the component model and add a realization to the exposed interface. This results in pretty arrows, but the class is in the component model. If I remove it from the model, the interfaces are still in the linked element list of the class, but i have found no way to add the interfaces to the model then, neither show in another way that this class implements those interfaces.

Any proposals how to accomplish that?

Answer 1

The second way DOES work. I now found the [...] button beside the textfield where to enter the name of the interface. It is possible to add an existing interface there.
