Hi Jim,
afaik jBPM4.4 is pretty much abandoned by jBoss, so you won't find a lot people using it...
did you check out org.jbpm.test.activities.GroupTimersTest?
Part of the testcase looks like this:
<transition name='timeout' to='escalate'>
<timer duedate='2 hours' />
</transition>
so maybe using "timeout" instead of "timeout1" might help?
