Re: [rules-users] Fact insertion & retraction in working memory

I have tried using @expire feature for Errorflag, which I expect to get expired after 30s, instead of using timer for a rule. it seems to be working correctly for a single rule. declare ErrorFlag @expire(30s) errorCode : String end rule "first time" when $Error1:ErrorInfo(errorCode=="000000A1")from entry-point ErrorEntryPoint not ErrorFlag( errorCode == "000000A1" ) then insert( new ErrorFlag( "000000A1" ) ); // action retract( $Error1 ); end I then needed to use this approach for mutiple rules, hence I declared the string field in this Errorflag for holding the rule name. declare ErrorFlag @expire(30s) errorRuleFlag : String end rule "first_Rule" when $Error1:ErrorInfo(errorCode=="000000A1")from entry-point ErrorEntryPoint not ErrorFlag( errorRuleFlag == "first_Rule" ) then insert( new ErrorFlag( "first_Rule" ) ); // action retract( $Error1 ); end rule "Second_Rule" when $Error1:ErrorInfo(errorCode=="000000A2")from entry-point ErrorEntryPoint not ErrorFlag( errorRuleFlag == "Second_Rule" ) then insert( new ErrorFlag( "Second_Rule" ) ); // action retract( $Error1 ); end I expected that it would create different instance of ErrorFlag & counting of 30s for each of instance would start when it was 'new' created in Then part. However, with this approach only first rule worked. I ended up declaring individual errorflag for each of the rule. I am trying to understand it's (@expire) actual working & what did I miss on when I expecetd it work with single declaration & mutiple instances? -- View this message in context: http://drools.46999.n3.nabble.com/Fact-insertion-retraction-in-working-me...
