------------------------------------

             Summary: Query code generation neglects query parameter(s)
                 Key: DROOLS-4604
                 URL: https://issues.jboss.org/browse/DROOLS-4604
             Project: Drools
          Issue Type: Feature Request
          Components: core engine
    Affects Versions: 7.27.0.Final
            Reporter: IVAN ZILOTTI
            Assignee: Mario Fusco


The Drools _query_ code generated by the test method below is not including the query parameter ({{String eventId}}) specified via {{PackageDescrBuilder}}.

Note that parameters to Drools _functions_ constructed through the same process are correctly included. See _org.drools.compiler.lang.api.DescrBuilderTest#testFunctions_.
 
h3. Generated code
{code:java}
package org.test.rules 

import org.test.event.TemporalEvent

query "getTemporalEventById"
    TemporalEvent( id == eventId ) from entry-point "TemporalEventStream" 
end
{code}

h3. Test
{code:java}
    @Test
    public void testFluentQuery() {
        PackageDescrBuilder packBuilder =
                DescrFactory.newPackage()
                        .name("org.test.rules")
                        .newImport()
                            .target("org.test.event.TemporalEvent")
                            .end()
                        .newQuery()
                            .name("getTemporalEventById")
                            .parameter("String", "eventId")
                            .lhs()
                                .pattern( "TemporalEvent")
                                    .constraint("id == eventId")
                                    .from()
                                        .entryPoint("EventStream")
                                .end()
                            .end()
                        .end()
                    .end();

        String query = new DrlDumper().dump(packBuilder.getDescr());
        System.out.println(query);
    }
{code}
