Re: [rules-users] Entry-Points can cause NullPointerExceptionand/or no rule firing

Hi Greg! Thanks for your quick answer. I’m having some trouble with absence of events in Drools (I’ve send some emails on the mailing list regarding that) and I personally think it’s some kind of bug (mine or, probably, drools). So, I’m looking for some help. Instead of explaining all over again, I just point the issue out. Sorry about this mess, too much time around this problem J Thanks, once again!

First of all, I’m running Drools 5.1.0.SNAPSHOT on Windows and Eclipse 3.4. I’ve submitted a Jira Issue (https://jira.jboss.org/jira/browse/JBRULES-2511 <https://jira.jboss.org/jira/browse/JBRULES-2511> ): “ I've got a system that receives transactions. I want to implement the following rules: - raise an alarm(alarm event) when there aren't any transaction for an hour (or more); - if there's an alarm, no more alarms should be raised; - if there's an alarm and the system receives a transaction, that alarm should be retracted and the system should send an recovery event. I've implemented the rules this way: - ***start*** rule to insert an "EngineStart" event when the rules engine starts - ***notrx_after_start*** rule to detect absence of transactions during the first hour - ***notrx_after_trx*** rule to detect absence of transactions (during one hour) after last transaction - ***rearm*** rule to detect transactions and rearm the system. I made a Maven project with junits, which inserts transactions at specific time, in order to raise the desired events. Two set of tests were made: - the rules defined in "default" entry-point: the correspondent junit gives a NullPointerException in DefaultAgenda - the rules defined in "incoming" entry-point: the correspondent junit doesn't activate the ***rearm*** rule “ The issue has an attachment with junits and rules to play with.
