Hi hendrik,

Thank you for using JUDE.

This error message appears when you try to combine two different Interefaces.

There are two ways to represent a combined Interface like the figure below.






Method 1 :
1. Create a Component diagram, Component0, Component1, and Provided Interface to Component0
2. Create a Usage Dependency from Component1 to Interface0

















Method 2 :
1. Create a Component diagram, Component0, Component1 and Required Interface to Component1
2. Create a Realization from Component0 to Interface0
















Cheers,
Satomi
