Mark Proctor commented on JBRULES-1153:
---------------------------------------

This now works. BaseNode no longer has the field hasMemory() intead ObjectSink and TupleSink now have isObjectMemoryEnabled() and isTupleMemoryEnabled(). I then configure the various nodes to make things work for sequential execution and querries. So querries no longer use memory, and thus DroolsQuery object does not need to be retracted.
