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.
