[jboss-jira] [JBoss JIRA] (DROOLS-922) Drools Loops with this CEP test

[Mario Fusco (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-922?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mario Fusco resolved DROOLS-922.
--------------------------------
    Resolution: Rejected


I believe the loop is the behaviour you should expect with that given rule set. The sequence of events there is:

* insertion of MyMessage( "ATrigger" )
* fireAllRules executes "Rule A Start" that inserts "A-StateGuard" and "A-StartTimer" 
* insertion of MyMessage( "BTrigger" )
* fireAllRules executes "Second State" that 
# inserts "RuleFlow ended" 
# triggers rule "CleanUp" that remove all the 3 Strings
# since there's no String "A-StartTimer" rule "Rule A Start" can be triggered again inserting "A-StateGuard" and "A-StartTimer" 
# the insertion of "A-StateGuard" also triggers again "Second State"

... that closes the loop that is executed until the timed rules remove "A-StartTimer". 

I think you could achieve what you wanted by NOT deleting the String "A-StateGuard" in the consequence of rule "CleanUp".

Please reopen this ticket if you think that I'm overlooking something.

> I want to emulate the workflow style rules using state guards. When I run the attached, it loops many times until the incoming event expires.
