Vitor,

Please stop replying to posts with unrelated topics and just changing the title, it messes up the threaded view in most people's email app. See here for more details on netiquette:

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!

JIRA issues are for reporting bugs in drools.  Is there a bug you're reporting or do you want help with this particular problem?

Hi 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):

"

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.

 

T.I.A.
