Hi all
I'm trying to use SCXML for a project (i have to realise an implementation
of the MMI w3C spec).
In my example, I want to assign the name of the event at a var.
Somethink like this :
<state id="getCity">
<transition event ="*" target="checkCity" name="evt">
<assign location="${Data(city,'root/mycity')}" expr="${event}" />
</transition>
</state>
Somebody know how can i do this ? and is it possible to do this ?

In the latest release (v0.9), a little bit of work is required to do
such a thing. Add the event name (a bit redundantly) as a property of
the event payload when you create the TriggerEvent. Say that property
is called "name", then it can be accessed in the <assign> above with
the following expr attribute:
expr="${_eventdata.name}"
In subsequent (future) releases, this information will be available
using the new "_event" variable specified in the latest SCXML Working
Draft like so:
expr="${_event.name}"
There will be no need to rely on the payload to transmit the name at
that point.
