[rules-users] issue with 'forall'

Hi, I have encountered the following problem with the latest Drools 5.1 SNAPSHOT I've created a sample Drools project and replaced the Sample.drl with the following: --Sample.drl-------------------------------------- package com.sample import com.sample.DroolsTest.Message; rule "Hello World" when forall( Message( ) Message() ) then System.out.println("executed"); end -------------------------------------------- If I run the sample application like this everything is fine - "executed" is printed. However, if I modify the main method and insert some additional fact just before the message fact is inserted, like this: --DroolsTest.java----------------------------------- ..... ksession.insert(new Object()); ksession.insert(message); ..... ----------------------------------------------------------- then the rule won't fire any more. Please note that if you change the fact insertion order (first the message then the Object) it will work as expected. Is this a bug or am I missing something? I can file a JIRA if needed. Thank you!
