The Commons SCXML version and the relevant driver (Java) code will help towards answering -- we know this works, so we'll need to know whats being done differently. Bear in mind that the timers execute as daemons. I suggest trying your example standalone [1] first, and we'll go from there. As an aside, in the markup below, <log> is nested in <send> which isn't legal, so the nested <log> will be ignored. -Rahul [1] http://commons.apache.org/scxml/guide/testing-standalone.html > --------------------------- > <scxml version="1.0" initialstate="167" xmlns:cs=" > http://commons.apache.org/scxml"; xmlns="http://www.w3.org/2005/07/scxml";> > <state id = "167"> > <transition target="StateA"/> > </state> > <state id ="StateA"> > <onentry> > <log label="Renegade" expr="'Entering state: A'"/> > <send sendid="1" event="'ToB'" delay="'1000ms'"> > <log label="Renegade" expr="'Timer starting...'"/> > </send> > </onentry> > <transition event="ToB" target="StateB"/> > </state> > <state id="StateB"> > <onentry> > <log label="Renegade" expr="'Entering state: B'"/> > <send sendid="2" event="'ToA'" delay="'2000ms'"> > <log label="Renegade" expr="'Timer starting...'"/> > </send> > </onentry> > <transition event="ToA" target="StateA"/> > </state> > </scxml> > --------------------- > > The output when this is run is simply: > 2009-apr-14 13:08:57 org.apache.commons.scxml.model.Log execute > INFO: Renegade: Entering state: A > 2009-apr-14 13:08:57 org.apache.commons.scxml.env.SimpleScheduler send > INFO: send ( sendId: 1, target: null, targetType: scxml, event: ToB, params: > null, hints: null, delay: 1000) > > best regards > //Linda > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
