Edson Tirelli resolved JBRULES-1171.
------------------------------------

    Resolution: Cannot Reproduce Bug

I was not able to reproduce the problem in the trunk. Anyway, I added the following integration test:

==============
package org.drools;

global java.util.List results;

rule "test from nested accessors"
when
    $oi : OrderItem( seq == 1 )
    $os : Order.OrderStatus() from $oi.order.status
then
    results.add( $os );
end
==================

Code to run is:

==================
    public void testFromNestedAccessors() throws Exception {
        final PackageBuilder builder = new PackageBuilder();
        builder.addPackageFromDrl( new InputStreamReader( getClass().getResourceAsStream( "test_FromNestedAccessors.drl" ) ) );

        final RuleBase ruleBase = getRuleBase();
        ruleBase.addPackage( builder.getPackage() );

        final WorkingMemory workingMemory = ruleBase.newStatefulSession();

        final List list = new ArrayList();
        workingMemory.setGlobal( "results",
                                 list );

        final Order order1 = new Order( 11, "Bob" );
        final OrderItem item11 = new OrderItem( order1, 1 );
        final OrderItem item12 = new OrderItem( order1, 2 );
        order1.addItem( item11 );
        order1.addItem( item12 );
        
        workingMemory.insert( order1 );
        workingMemory.insert( item11 );
        workingMemory.insert( item12 );
        
        workingMemory.fireAllRules();
        
        assertEquals( 1,
                      list.size() );
        
        assertSame( order1.getStatus(),
                    list.get( 0 ) );
    }
==================

I'm closing this ticket, but if it is still a problem for you, please reopen the ticket and add a self contained test showing the problem.
