[rules-users] [droolsflow] JPAVariablePersister - Multiple Entries for Variables passed into ForEach

[Kris Verlaenen]

Bill, 

Is it possible that your ForEach is starting a subprocess where there
also is a process variable role?

Looking at the screenshot, it appear you are indeed persisting the same
Role twice (leading to two JPAPersistedVariables), both referring to the
same entity (id=1).  But the processId seems to be different, and the
name of the variable as well, which seems to indicate that the variable
is persisted in separate processes.  In that case, it would make sense
to have two JPAPersistedVariables.
