[rules-users] bug in "accumulate"

Folks, Using 4.0. Think I found a bug in accumulate. The variables defined inside <source pattern> cannot be recognized inside of other parts of accumulate (action, result) f.e. rule ... when o : Date from accumulate ( Parent( h : height ) , init(;), action(;), reverse(), result( $h ) ) then ... end Produces : $h cannot be resolved Stack trace: at org.drools.rule.Package.checkValidity(Package.java:408) at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:288) at com.lear.rules.RuleBaseFacade.getRuleBase(RuleBaseFacade.java:46) -Sergey ********************** ** LEGAL DISCLAIMER ** ********************** This E-mail message and any attachments may contain legally privileged, confidential or proprietary information.
