      This accumulate statement

      accumulate(
    $SNTLocation0:SNTLocation(this memberOf $SNTLine.locations)
    and
    (
        PolicyLocation(this!.id==$SNTLocation0!.address!.id,
                       (this.addressLine1 == "16 Royal Crest Drive"))
        or
        PolicyLocation(this!.id==$SNTLocation0!.address!.id,
                       (this.addressLine2 == "Apartment 11"))
    )
    and
    $collection0:SNTLocation(this==$SNTLocation0)
    ;
    $count1: count($collection0)
    ;
    $count1 > 1
)

      fails with "BUG: Can't build a rete network with an inner OR group element".

      I understand that this particular example could be rewritten to remove the OR by using a single PolicyLocation pattern, but it is just an example. My application generates drools code from user input and so the expression in the accumulate statement could be any logical expression using properties from the domain objects.
