I made a URCap with multiple child nodes, and it works fine.

Now I am working on an additional URCap, which should only be a single node, but how is that done? If there isn’t any child nodes, it is marked as not “finished” in the program tree.

all you need to do is return false at the overridden isChildrenAllowed() function of your urcaps programNodeService.

I was looking inside Contribution, and found nothing…

This was way simpler than I expected it to be 😊
