We think the way to handle this, and other issues, is to have special
event facts, which can then be matched:
Otherwise()
OnWorkingMemoryEnter()
OnWorkingMemoryExit()
OnAgendaGroupEnter()
OnAgendaGroupExit()
OnAgenda* can take an AgendaGroup name as a field constraint. So how
will this work? With Otherwise() we will assert this fact if after a
fact is modified or asserted and no new activations are created. We will
also extend the event model to support the other events, and again
expose them by a specially asserted fact. OnWorkingMemoryEnter() will be
asserted when a WorkingMemory is first created and Exist when the Agenda
is empty and we are returning back to the main java process. OnAgenda*
is for when an AgendaGroup gain and lose the focus. Hopefully this will
solve a number of problems.

A follow-up question…
What the heck is the DRL way of saying (ignore my shorthand)
When
x
Then
doSomething
When
y
Then
doSomethingElse
Otherwise
doExceptionHandling
I need this for a routing example.
