Mark Proctor closed JBRULES-1220.
---------------------------------

    Fix Version/s: 4.0.2
       Resolution: Cannot Reproduce Bug

I have just added an integration test for a custom global resolver, for the type of problem you just showed me, it works ok for me. Here is the code snippet.

    public void testCustomGlobalResolver() throws Exception {
        final PackageBuilder builder = new PackageBuilder();
        builder.addPackageFromDrl( new InputStreamReader( getClass().getResourceAsStream( "test_globalCustomResolver.drl" ) ) );
        final Package pkg = builder.getPackage();

        final RuleBase ruleBase = getRuleBase();
        ruleBase.addPackage( pkg );
        final WorkingMemory workingMemory = ruleBase.newStatefulSession();

        final Map map = new HashMap();
        List list = new ArrayList();
        String string = "stilton";
        
        map.put("list", list);
        map.put("string", string);
        
        workingMemory.setGlobalResolver( new GlobalResolver() {
            public Object resolveGlobal(String identifier) {
                return map.get( identifier );
            }

            public void setGlobal(String identifier,
                                  Object value) {
                map.put( identifier, value );
            }
            
        } );

        workingMemory.fireAllRules();

        assertEquals( new Integer( 5 ),
                      list.get( 0 ) );        
    } 

-------------------------------------------------------------
package org.drools.test;

import org.drools.Cheese;

global java.util.List list
global java.lang.String string


rule "global rule test"
    when
        eval( "stilton".equals( string ) )
    then
		list.add( new Integer(5) );
end

> 				System.out.println("!!!!!!!!!! set " + identifier);
> 				ci.setVariable(identifier, value);
> 			}
> 		});
> And a rule file that serves as test
> package org.jbpm.action
>  
> import org.jbpm.resolveraction.Customer;
> import org.jbpm.resolveraction.Order;
> import org.jbpm.context.exe.ContextInstance;
> global java.lang.String shipper

> 	then
> 		System.out.println(shipper);
> 		drools.getWorkingMemory().setGlobal( "shipper", "FEDX" );
> 		System.out.println("ship via FEDX " );
> end
> The output of the test is as expected
> 11:50:51,226 INFO  [STDOUT] !!!!!!!!!! resolve shipper
> 11:50:51,227 INFO  [STDOUT] None
> 11:50:51,227 INFO  [STDOUT] !!!!!!!!!! set shipper
> 11:50:51,227 INFO  [STDOUT] ship via FEDX 
> But if we modify the rule file to
> package org.jbpm.action
>  
> import org.jbpm.resolveraction.Customer;
> import org.jbpm.resolveraction.Order;
> import org.jbpm.context.exe.ContextInstance;
> global java.lang.String shipper
> rule "Determine Shipper"
> 	when
> 		eval ("None".equals(shipper))
> 		Customer( region >= 1 )
> 		Order( totalAmount >= 0 )
> 	then
> 		System.out.println(shipper);
> 		drools.getWorkingMemory().setGlobal( "shipper", "FEDX" );
> 		System.out.println("ship via FEDX " );
> end
> then nothing is printed - no attempt to resolve shipper global variable
