[jboss-jira] [JBoss JIRA] Created: (JBRULES-837) Collect keyword matches two conflicting rules

Collect keyword matches two conflicting rules --------------------------------------------- Key: JBRULES-837 URL: http://jira.jboss.com/jira/browse/JBRULES-837 Project: JBoss Rules Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 3.1-m1 Environment: java 1.5 Reporter: Viktor Nordling Assigned To: Mark Proctor If you have two rules: rule "A" when $a : ArrayList( size:size == 2 ) from collect (Car()) then System.out.println("A: size = " + size); end rule "B" when $b : ArrayList( size:size == 3 ) from collect (Car()) then System.out.println("B: size = " + size); end And you put two Cars in working memory, both A and B will be fired. Since there are two cars in working memory, only rule A should be fired. If you change the order of the rules, or make rule A match size == 3 and rule B match size == 2, no rules will be fired instead. The only workaround found is to add some criteria for the Car, in ONE of the rules. If rule A for example is: rule "A" when $a : ArrayList( size:size == 2 ) from collect (Car(color == "RED")) then System.out.println("A: size = " + size); end Then only rule A will be fired. If the same criteria is also added in rule B, both rules will be fired again. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
