[Commons SCXML] ECMAScript support

[Simon Gillet <si...@student.uclouvain.be>]

Hello,

I'm a student and I'm doing my thesis about CCXML and SCXML.
I'm trying to do some tests with "Commons SCXML" but I'm surprised.
It seems that it doesn't support ECMAScript expressions in any place.
It use JEXL en EL.
I believed that a SCXML interpreter MUST support ECMAScript compact  
profile.
Is there a way to enable commons SCXML to parse ECMAScript expressions?

Thank you

Those two out of the box, yes.

True, thats what the current WD says. However, the datamodel module of
the spec is in reasonable amount of flux (as I understand it), and I'm
not sure if that statement will hold for the next WD. I intend to
wait.

Yes, but with some work. A corresponding ECMAContext and ECMAEvaluator
will need to be authored. More on that here [1].
