Am I right here? If you mean finding available event names/patterns (see 3.12.1 in https://www.w3.org/TR/scxml/#events) for a transition, there seems to be no convenient method unless you implement a utility method by yourself based on SCXMLSemanticsImpl. But, basically the specification is more complex than your simple use case. I guess that's why there has been no convenient utility yet.

I'm not really sure that SCXMLExecutor should report an error at the moment when it cannot find any transition associated. I couldn't find anything clear about that in the specification. If you find something, please let us know. ;-) > Do you see in the future, this will be supported by SCXML ?

Again, I'm not really sure it has to report an error when not finding a transition to proceed on an event. It doesn't sound like an error to me, but maybe a warning in that case.
