[rules-users] Insert and Retract from drools server in one call?

[Wolfgang Laun]

Perhaps this is the answer: Just add a rule that retracts the "initial
fact(s)".

Your description confuses me. At one point you use the plural, then the
singular. What does "initial" mean in your parlance? Session-initial or
client-request-initial? What is the lifetime of the stateful session? Longer
than the processing of a single event?
