How do I throw a signal using an event listener, and set this up inside modeler? I can see it in the docs, but it looks like xml editing is required. I can’t see how to edit the xml inside the modeler.

The goal is to activate a signal catching event when another event ends. I don’t know how to code java, so I’m challenged here. I know that I can create a new route with an intermediate signal event and end event, but I’d like to do this in the process a lot and so an event listener would make for a cleaner diagram.

Hi!

You can download the flow and edit the xml in your favourite editor and later upload to modeler.

Is a good idea learn some of Java for build in Flowable… 😉
