[rules-users] From v 3.0.6 to 4.0.0

Hi everyone, I am new to this mailing list, I've had a quick look at archives and didn't find anything ont this subject but sorry if this has allready been underlined. Here is my problem, while I was doing some test on v3.0.6, 4.0.0 came out, so I started to migrate on the new version. Then I found out an unexpecteed behavior on the 4.0.0. I have been compiling both with Java 5 and running whith Java 1.5.0_11. And I used versions with dependencies on both tests. I have made an exemple for you to make it as clear as possible, here is the rule : --------------------------------------------------------------------------------------- package rules rule "TwoCheeses" when $cheese1 : Cheese(); $cheese2 : Cheese(); then System.out.println($cheese1); System.out.println($cheese2); System.out.println("TwoCheeses"); end --------------------------------------------------------------------------------------- When I run it on V3.0.6, with this code : --------------------------------------------------------------------------------------- package rules; import java.io.InputStreamReader; import org.drools.RuleBase; import org.drools.RuleBaseFactory; import org.drools.WorkingMemory; import org.drools.compiler.PackageBuilder; public class Cheese { public static void main(String[] args) throws Exception{ PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl(new InputStreamReader( Cheese.class.getResourceAsStream("rule.drl"))); RuleBase ruleBase = RuleBaseFactory.newRuleBase(); ruleBase.addPackage(builder.getPackage()); WorkingMemory workingMemory = ruleBase.newWorkingMemory(); Cheese cheese = new Cheese(); workingMemory.assertObject(cheese); workingMemory.fireAllRules(); } } --------------------------------------------------------------------------------------- The rule doesn't fire, which is normal AMHA since only one Cheese object is asserted to the WM When I run it on V4.0.0, whith this code : --------------------------------------------------------------------------------------- package rules; import java.io.InputStreamReader; import org.drools.RuleBase; import org.drools.RuleBaseFactory; import org.drools.StatefulSession; import org.drools.compiler.PackageBuilder; public class Cheese { public static void main(String[] args) throws Exception{ PackageBuilder builder = new PackageBuilder(); builder.addPackageFromDrl(new InputStreamReader( Cheese.class.getResourceAsStream("rule.drl"))); RuleBase ruleBase = RuleBaseFactory.newRuleBase(); ruleBase.addPackage(builder.getPackage()); StatefulSession statefulSession = ruleBase.newStatefulSession(); Cheese cheese = new Cheese(); statefulSession.assertObject(cheese); statefulSession.fireAllRules(); } } --------------------------------------------------------------------------------------- Now the rule fires and $cheese1 $cheese2 have the same reference. I have been searching in all docs, this modification of behavior doesn't seem to be expected, has anyone noticed this? Thanks for your help. Chris
