Mario Fusco commented on DROOLS-864:
------------------------------------

I tried again with the test case I'm pasting below, but I still cannot reproduce your issue. Note that I also tried to use just 'happy' instead of 'happy == true" and I gave a run also to the negative case trying both "happy == false" and "!happy". Everything worked as expected.

Please provide a self contained reproducer for this issue or I'll have to flag this ticket as not reproducible.

{code}
    @Test
    public void testBooleanFieldOnQuery() {
        String str =
                "import org.drools.compiler.Person\n" +
                "query \"happy persons\"\n" +
                "    Person(happy == true)\n" +
                "end\n";

        KieSession ksession = new KieHelper().addContent(str, ResourceType.DRL)
                                             .build()
                                             .newKieSession();

        Person p1 = new Person("me");
        p1.setHappy( true );
        ksession.insert(p1);

        Person p2 = new Person("you");
        p2.setHappy( true );
        ksession.insert(p2);

        Person p3 = new Person("he");
        p3.setHappy( false );
        ksession.insert( p3 );

        org.kie.api.runtime.rule.QueryResults results = ksession.getQueryResults( "happy persons" );
        assertEquals( 2, results.size() );
    }
{code}

> Recently, I have been upgrading from Drools 4.0.4 to 6.2.0 and I am having trouble with a boolean field/property in a query. I have a field called selected in the IntentionNode class (the field used to be called enabled but I renamed it just in case of a conflict with the keyword). The query returns 22 results, two of which are selected. However, the query should only return 20 (the ones that are not selected only). If I change the query to only returned the selected nodes, I get no results.
> After reverting back to 4.0.4, everything works. Either this is a regression or there is some new API or language construct that I am not using in the intended way.
