Hi,

I am using Papyrus from Eclipse Luna for modeling and Moka for model execution. Even though, I could execute sample model available at https://wiki.eclipse.org/Papyrus/UserGuide/ModelExecution using Moka; this model uses only activities.

And, when I tried to execute my own state machine based model; moka failed with error "An unexpected error occurred during execution. See error log for details". Here I have couple questions:

1. Does moka support model execution with state machine? If yes, is there any sample model available to try out?
2. Where can I find "error log" mentioned in moka error message? I checked papyrus console etc., but there were no errors.

Thanks,
Abhijit Deshpande

Not yet: State Machines are not part of fUML (Which currently includes Class, Activities, and an extension for Composite Structures). However, there is some work in progress for adding a StateMachine extension in fUML.

Hi Camille,

Thanks a lot for the quick response. So, is there any other way (tool) to execute state machine in Papyrus?

Regards,
Abhijit

Hi Abhijit,

The recently proposed Papyrus for RealTime project will be able to generate code to execute a state machine, albeit with some limitations. However, you'll have to wait for the Mars release (June 2015) for the first release.

Hello,

I am bringing back this topic because I would like to know if now it is possible to execute state amchine diagram in Moka. When I try to do it I have the same error as mention in the very first post.

Also, if it is now possible to simulate, is it possible for the state machine to communicate between each other through signals?

Thank you.

Albert

Hello Albert,

Yes it is now possible to simulate State Machine Diagrams.

Concerning the exception you get, can you give us a stack trace ? Can you check that your State Machine property isActive has been set to true ?

Best regards,
Pauine

Hello Pauline,

Indeed, I did not activate the isActive property, thank you!

Pauline,

Is there any documentation on how to do this? Simulating state machine diagrams is something that would be of great benefit to me but I have absolutely no idea how to even begin doing this.

Thanks!

Hello,

We are sorry but this documentation has not been written yet because of projects constraints.

Brest regards,
Pauline

Hello,

According to its documentation MOKA is compliant with PSSM 1.0 which is defined on top of UML 2.5.1.

However it looks like the Eclipse implementation of UML is still stuck on 2.5 that is not compatible with 2.5.1 State Machines.

How to deal with that?

Hi,
Papyrus is based on UML2.5 So MOKA should be based on 2.5 also.
In the norm of PSSM 1.0, I read
"Syntactically, this specification extends fUML with a (large) subset of the
abstract syntax of state machines as given in the OMG Unified Modeling Language specification [UML] (Clause 14, for
UML 2.5 and later)" page 1 or 13 with a viewer.
So I think that this is not a mistake to say that Moka is compliant with PSSM1.0 and UML2.5.

Hi Patrick,
That's a good point... And maybe an issue in the specification. I'll cross-check this with Ed S. because, to me, v2.5.1 was issued specifically on requests coming from the PSSM working group! :-)
