When you instantiate the TriggerEvent, use the three argument constructor to add event payload: http://commons.apache.org/scxml/0.9/apidocs/org/apache/commons/scxml/TriggerEvent.html#TriggerEvent(java.lang.String, int, java.lang.Object) Then, you may refer to the payload Object as _eventdata (in v0.9, in next release it will change to _event.data as the spec now requires). Here is an example from the test suite that uses event payload to determine transitions to follow; so you can look up syntax (see parent directory for more samples, syntax depends on EL in use): http://svn.apache.org/repos/asf/commons/proper/scxml/trunk/src/test/java/org/apache/commons/scxml/env/jexl/eventdata-02.xml -Rahul > Cheers, > Artem --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@commons.apache.org For additional commands, e-mail: user-h...@commons.apache.org
