[rules-users] confused on when to call fireAllRules

Hi, I'm trying to add some functionality to my 4.0.7 based project and am realizing I don't understand some basics as well as I thought I did. Until now, I've been using a very simple model: create session, insert facts, fire rules, destroy session. My new functionality needs to use a long lived session. I also may find the duration feature useful so I searched through the examples and found the TroubleTicketExample. Now what has be confused is that example shows rules firing AFTER control has been returned from the fireAllRules() call. I tried to create something similar - call fireAllRules, then call session.update(han, obj) - but nothing happens. If I call fireAllRules again (after the update) then my rule fires as expected. My test didn't use any duration statement. Is that the magic in the TroubleTicketExample? If so, then how does one have a clue as to whether one needs to call fireAllRules after an update or not (i.e. no way to tell if a duration rule is keeping it running)? Obviously I'm missing some basic understanding here. Please enlighten me. Thanks, Charles Binford
