Creating relationship in Relationship Matrix: No stereotype '' found in profile

[PeteC]

I believe the below is a bug and have reported it as such, but just asking here in case I have made a mistake:

1. Create a custom MDG.
2. Include a connector stereotype generalised from another MDG (I called it Test and generalised it from SysML1.4::Allocate). I also tried Archimate3::ArchiMate_Serving.
3. Use the MDG to create a model. I turned off Strict Connector Syntax.
4. Manually create a relationship to prove that it can be created between two elements.
5. Open the Relationship Matrix, ensuring that the MDG is in the perspective view.
6. Right click on the Relationship Matrix and select Create a new relationship
7. Select the relationship created above.

The fault is a dialog at step 7 of the form "No stereotype '' found in profile "MyMDG" Command MyMDG::(UML:".

If the MDG is modified so that the same relationship is extended from a metaclass then it works.

I'm not sure why the stereotype is not found my profile when it works correctly creating the relationship manually.

To follow up on this, Sparx provided me with some screenshots and they had both generalised the custom stereotype from SysML1.4 AND extended it from an Association metaclass. Then it works.
