State machine diagram [message #1824301]

Hello All,

For use in designing C based software I am trying to make use of Papyrus/Moka to model and simulate a single statemachine. Since fixed delay's on some of the state transitions are needed I've started out trying a simple_fsm (see attached screenshot) that should switch between ON- and OFF state at regular delays.
Sadly, Moka keeps complaining about a Java.NullPointerException. After trying for days now, and reading a lot on the internet I now kindly ask you all for a clue.

Since there is no class related to the single state diagram I have set the status to ACTIVE, and I have tried using both the org.eclipse.papyrus.moka.fuml.statemachines engine as well as the org.eclipse.papyrus.moka.timedfuml engine. But both without success. Without the delays the simulation works ok by the way.

Could anyone give me a hint please. I'm using Papyrus Version: 2020-03 (4.15) with the MOKA plugin from the marketplace.

Looking forward to your reply !

Peter

Peter, I won't be of much help given I just downloaded eclipse, sysml 1.6 and then moka and same as yourself. I did notice that if I did do something like have a sm with only an initial and a final state it "worked", though admittedly that would not be very useful. I have not found any useful guides, have you?
