Subject Re: [SCXML] How to obtain a collection of valid events
Date Sat, 21 May 2016 01:36:20 GMT
Thank you for replying.
>From what you said, I can conclude that this is not supported or
offered by SCXML. Am I right here?
AFAIR an FSM should report if the token is recognized or not, and not
just complete the transition/ignore the token silently.. If I am right
here as well, then this use case is not specific to me.
Do you see in the future, this will be supported by SCXML ? Should we
open a JIRA ticket ?

Thank you
