[rules-users] Drools Flow 5.1.0.M1 - Persistence - WorkItemInfo Entity

I have a question related to the (Drools Flow 5.1.0.M1 - Persistence) on the data that gets stored as part of the org.drools.persistence.processinstance.WorkItemInfo. a) If I am using variable persistence strategy - and I pass a JPA Entity(stored in its own table) to a session.startProcess("", map) and map this entity variable to a parameter in the work item node - then this entity will get stored in the WorkItemInfo table as a part of the serialized form in the column (workItemByteArray). So if that is true we have got the same data stored twice? Is this correct? b) If "a" is true how can we avoid storing in the WorkItemInfo - is there somehow we can map the JPA entity to the WorkItemInfo - so that it doesn't gets stored twice? Thanks Vijay
