Integration with jBPM does not work
-----------------------------------

                 Key: JBRULES-1220
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1220
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 4.0.1
            Reporter: Jiri Pechanec
         Assigned To: Mark Proctor
            Priority: Minor


We had a code that intgrates JBoss Rules Global Resolver with jBPM variable pool

		workingMemory.setGlobalResolver(new GlobalResolver() {
			private static final long serialVersionUID = 1L;
			public Object resolveGlobal(String identifier) {
				System.out.println("!!!!!!!!!! resolve " + identifier);
				return ci.getVariable(identifier);
			}
			public void setGlobal(String identifier, Object value) {
				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

rule "Determine Shipper"
	when
		Customer( region >= 1 )
		Order( totalAmount >= 0 )
	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
