Imported edges do not support overriding behavior

[darets97]

Context

We are working on a customer specific extension to the UML2 activity diagram from UML Designer that relies heavily on Guards defined on ControlFlowEdge. For this reason we have created a layer, inside of which we define an Edge Import that we use to modify the Center Label to display the edge's guard rather than it's name. Unlike Node Imports, we are unable to change the Behavior (found in the Behavior tab in the Sirius Specification Editor), and as a result we cannot change the Double Click Description to display a custom window including a guard, or the Label Direct Edit to directly edit the guard.

Expected behavior

When clicking on an imported edge in the Sirius Specification Editor, the Properties tab should allow the Behavior to be changed for Edge Import similar to Container Import .

The Properties tab for Edge Import without the Behavior tab present

The Properties tab for Container Import with the Behavior tab present

Solution
Add a Properties tab for Edge Import in the Sirius Specification Editor

This would be great to have resolved!

Indeed, EdgeMappingImports can only be used to define conditional styles. The behavior could be improved, but this kind of development is not part of our roadmap. As this feature is rarely used, there's hardly any chance of this enhancement being developed by our team without funding.

Otherwise, I suggest you find another solution, even if it means duplicating some mappings. There's a good chance this will be as efficient, even if it's not very aesthetic.
