How to create an empty / silent transition

Dear community,

I wrote my own process discovery algorithm called uncertainty marker that can be found in the current Runnerup package, in which I want to add an empty/silent/unobserved transition. I did so by just adding a transition with the label "-" and colored it black.

Unfortunately that result in some issues when I try to measure the quality of the resulting model in conformance checking. Is there a way to add a real empty transition that really allows skipping ?

Best regards,



  • Hi Oliver,

    I just asked quickly and there should be a 'setInvisible(true)' method on a transition instance. So no need to 'hack' with '-' and colors :)
