I have a fairly complicated drools program and I want to introduce temporal reasoning to it. I spent a bit of time writing some proof-of-concept programs to get the feel of fusion and then tried to slowly introduce things into my original drools program. When I changed my program from using fireAllRules() to using fireUntilHalt() on a separate thread, I suddenly get failures in my unit tests. (My first thought was that there was a race condition between my unit tests and the thread calling fireUntilHalt() so I introduced a delay before my unit tests but no luck) Here are some of the behaviors I am seeing. 1) I occasionally get nullpointerexception from the thread running fireUntilHalt() 2) My lock-on-active rules aren't firing I have banged my head on this a while with no success. (I even tried putting fireAllRules() in a loop because of suggestions I saw but no luck and same behavior). My questions are, Is there a secret to using fireUntilHalt() that I am not aware of? Can anybody point me to where I can educate myself on its proper use? BTW no persistence and no spring in the code at this point. Thanks, in advance, for any help you can provide.
