looks like I have forgot to put a pom.xml file into add-on, or rather I was unaware that I should add one. I’ll see to it that the next version will have this, then the dependency management should function properly.
In the meantime I think you just need to add the PopupButton dependency to your own pom.xml by hand.
Replying to myself - there’s now a new version (0.8.1.v7) in the Directory. This includes the pom.xml which should fix the dependency issue. Please try it out and let us know if it worked
Found out why I did not find PopupButton add-on: I used the top-right search field, not the one on left-side (which I simply haven’t seen until now) :bashful:.
