Mark Proctor commented on JBRULES-410:
--------------------------------------

I have fixed the bug, just writing a unit test for it now. The problem was two fold. Firstly DroolsQuery did not implement equals and hashcode. The other problem was the attachQuery method was not using the attachNode method to add the nodes its generating.

> When using the queryResults() from the LHS of the rules we are getting a null for the first Fact asserted, and then the query size shows the correct value for the rest of the facts.   We observed that this is a problem in the following cases:
> 1.  LHS Fact does not have any constraints -- Event() vs.  Event(state == "emit")
> 2.  Multiple queries in the LHS fail -- just returns null results.  In order to test this please uncomment query "Total ent1 events" and rule "ENT1 emit with multiple queries"
> 3.  Multiple queries in the rule file (i.e. two queries defined).  One rule uses one query and the other rule uses the other query.  The first rule/query will work, but the second rule/query will fail.
