Hi again Jasmin,
You understand the issue correctly. I used a "Set Value" activity instead of an "Decision Point" and then it worked perfectly. However I don't understand why the User Assignment cannot "see" the end branch/join gateway. In short, I don't think it should be necessary with an extra activity, is this a known bug or just a glitch?
Thanks for the help by the way
