When I run the following flow in JBoss 5.1, the Person entity gets duplicated in one of the nodes. The Person entity is a hibernate managed object that is already persisted to the DB. Before snapshot I would modify the entity in the rule and read the entity value in the flow to set the Human Task Actor. This worked in the milestone release but no longer works in the current snapshot.
I do not see the same behavior when running from eclipse with a non hibernate object. Note: I am using a groovy Person object in my flow that is a subclass of PersonBase(). I use the PersonBase() in my rule because the rules engine does not register the Person object as a fact it registers the PersonBase superclass for some reason. This is likely a separate issue, but I thought I would make you aware. <?xml version="1.0" encoding="UTF-8"?> <process xmlns="http://drools.org/drools-5.0/process"; xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"; xs:schemaLocation="http://drools.org/drools-5.0/process drools-processes-5.0.xsd" type="RuleFlow" name="Approval Flow" id="com.datacert.workflow.Base" package-name="com.datacert" version="1.0" > <header> <variables> <variable name="entityId" > <type name="org.drools.process.core.datatype.impl.type.ObjectDataType" className="java.lang.String" /> </variable> <variable name="currentApproverName" > <type name="org.drools.process.core.datatype.impl.type.ObjectDataType" className="java.lang.String" /> </variable> <variable name="entity" > <type name="org.drools.process.core.datatype.impl.type.ObjectDataType" className="com.datacert.apps.sampleapplication.models.Person" /> </variable> </variables> </header> <nodes> <ruleSet id="13" name="flight rules" x="272" y="280" width="80" height="48" ruleFlowGroup="approval" /> <end id="11" name="End" x="291" y="446" width="48" height="48" /> <start id="1" name="Start" x="289" y="15" width="48" height="48" /> <actionNode id="7" name="Read Variables" x="257" y="106" width="113" height="48" > <action type="expression" dialect="mvel" >System.out.println("********** currentApproverName:" + currentApproverName + " airline:" + entity.getlastapprover());</action> </actionNode> <actionNode id="10" name="Read Variables" x="250" y="359" width="131" height="48" > <action type="expression" dialect="mvel" >System.out.println("**************approver:" + currentApproverName + " airline:" + entity.getlastapprover());</action> </actionNode> <actionNode id="12" name="Set Variables" x="257" y="195" width="112" height="48" > <action type="expression" dialect="mvel" >entity.setlastapprover("southwest"); currentApproverName="approver1";</action> </actionNode> </nodes> <connections> <connection from="12" to="13" /> <connection from="10" to="11" /> <connection from="1" to="7" /> <connection from="13" to="10" /> <connection from="7" to="12" /> </connections> </process> package com.datacert dialect "mvel" import com.datacert.apps.sampleapplication.models.*; rule "Initial Approval" ruleflow-group "approval" when $p : PersonBase() then System.out.println( "******** setting approver in rules"); $p.setlastapprover("delta"); end Latest snapshot output - note you will see two approver: entries when there should only be one. 20:18:21,123 INFO [STDOUT] Hibernate: insert into SessionInfo (dirty, lastModificationDate, rulesByteArray, startDate) values (?, ?, ?, ?) 20:18:21,139 INFO [STDOUT] Hibernate: insert into ProcessInstanceInfo (externalVariables, lastModificationDate, lastReadDate, processId, processInstanceByteArray, startDate, state, OPTLOCK) values (?, ?, ?, ?, ?, ?, ?, ?) 20:18:21,139 INFO [STDOUT] ********** currentApproverName:null airline:southwest 20:18:21,139 INFO [STDOUT] Hibernate: update ProcessInstanceInfo set externalVariables=?, lastModificationDate=?, lastReadDate=?, processId=?, processInstanceByteArray=?, startDate=?, state=?, OPTLOCK=?

Do you have an example of where this seems to have been broken in the snapshot?
