[jboss-jira] [JBoss JIRA] Updated: (JBRULES-410) Issues when using the queryResults(). Not returning results as expected.

[Corey Ellis (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBRULES-410?page=all ]

Corey Ellis updated JBRULES-410:
--------------------------------

    Attachment: querytest.drl
                QueryTestDriver.java
                RuleTest_081006.zip

I attached the rules file, driver code, and also I zipped the entire project if that makes it easier.

Important files are querytest.drl, and QueryTestDriver.java

> 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"
