Chris Woodrow wrote: Hi, I would to share our experience about recent versions of Drools. We found out that 4.0.6 was out on last wednesday, so we decided to move up from 4.0.3 to 4.0.6. We made a few tests but we counted on the fact that backward compatibility was provided. On friday, I went on Drools website and found out that version 4.0.6 was replaced by 4.0.4 whithout any more explaination, I made a research on this list to find out that you had to make a roll back. At the same time we found out a drools bug on our app : Caused by: java.lang.NullPointerException at org.drools.base.evaluators.ObjectFactory$ObjectEqualsComparator.equals(ObjectFactory.java:561) at org.drools.base.evaluators.ObjectFactory$ObjectNotEqualEvaluator.evaluate(ObjectFactory.java:158) at org.drools.rule.LiteralRestriction.isAllowed(LiteralRestriction.java:61) at org.drools.rule.LiteralConstraint.isAllowed(LiteralConstraint.java:82) at org.drools.reteoo.AccumulateNode.assertTuple(AccumulateNode.java:156) at org.drools.reteoo.CompositeTupleSinkAdapter.propagateAssertTuple(CompositeTupleSinkAdapter.java:30) at org.drools.reteoo.FromNode.assertTuple(FromNode.java:90) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple(SingleTupleSinkAdapter.java:20) at org.drools.reteoo.JoinNode.assertTuple(JoinNode.java:107) at org.drools.reteoo.SingleTupleSinkAdapter.propagateAssertTuple(SingleTupleSinkAdapter.java:20) at org.drools.reteoo.JoinNode.assertObject(JoinNode.java:151) at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:22) at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:140) at org.drools.reteoo.CompositeObjectSinkAdapter.propagateAssertObject(CompositeObjectSinkAdapter.java:318) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:153) at org.drools.reteoo.Rete.assertObject(Rete.java:175) at org.drools.reteoo.ReteooRuleBase.assertObject(ReteooRuleBase.java:192) at org.drools.reteoo.ReteooWorkingMemory.doInsert(ReteooWorkingMemory.java:71) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:909) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:881) at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:682) We had to deploy our app on friday, so we decieded to rollback to 4.0.4 to find out that we had the same error. So we decided to rollback to 4.0.3, I went to the download section of your site, and found out that previous versions where just unavailable, which is unacceptable. Obviously, I found it on our SVN, but I wasn't very happy about this. Its "unnaccptable"? that we don't maintain free community resources at our descretion? If binaries are not available for download, you can always build your own: http://anonsvn.labs.jboss.com/labs/jbossrules/tags/ Or you could pay for priority support and full access to downloads. Btw the paid version also goes through extra levels of QA, by dedicated teams, so you avoid this. Here are my conclusions : - We are not going to change our version of Drools soon - Please give us access to previous versions Chris ________________________________ _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Its "unnaccptable"? that we don't maintain free community resources at our descretion? If binaries are not available for download, you can always build your own: http://anonsvn.labs.jboss.com/labs/jbossrules/tags/ You are right "unacceptable" was not the appropriate word, I am sorry about that and you are right about the own build. I did know about the priority support on the paid version but I did not know about downloads and QA. Do you mean that paid version does insure backward compatibility?
