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

                 Key: JBRULES-372
                 URL: http://jira.jboss.com/jira/browse/JBRULES-372
             Project: JBoss Rules
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: JBoss Rules 3.0.1 and JBoss Rules as downloaded from svn trunk as of 12/07/06 
            Reporter: Giovanni Cuccu
         Assigned To: Mark Proctor


here is the simple test case:

package simpletest;

public class AssertedObject {
	private String value;

	public String getValue() {
		return value;
	}

	public void setValue(String value) {
		this.value = value;
	}

	public AssertedObject(String value) {
		// TODO Auto-generated constructor stub
		this.value = value;
	}
	
	
}

package simpletest;


import simpletest.AssertedObject;

rule rule1
	when
	then
		assert( new AssertedObject( "value1") );
		assert( new AssertedObject( "value2") );
end

query "assertedobjquery" 
    assertedobj : AssertedObject( value=="value1" )
end

package simpletest;

import java.io.InputStreamReader;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Map;

import mit.rules.test.Prestazione;
import mit.rules.test.StrutturaErogante;

import org.drools.compiler.PackageBuilder;

public class TestQuery {
	public static void main(String[] args) throws Exception {
		// TODO Auto-generated method stub
	    final PackageBuilder builder = new PackageBuilder();
		builder.addPackageFromDrl( new InputStreamReader( TestQuery.class.getResourceAsStream( "testquery.drl" ) ) );
		
		final RuleBase ruleBase = RuleBaseFactory.newRuleBase();
		ruleBase.addPackage( builder.getPackage() );
		
		final WorkingMemory workingMemory = ruleBase.newWorkingMemory();
		fireRules(workingMemory);
		        
	}
	
	public static void fireRules(WorkingMemory workingMemory) {
		final WorkingMemoryFileLogger logger = new WorkingMemoryFileLogger( workingMemory );
		logger.setFileName( "log/testquery" );
		
		workingMemory.fireAllRules();
		QueryResults results = workingMemory.getQueryResults( "assertedobjquery" );

		if (results==null || !results.iterator().hasNext()) {
			System.err.println("Empty list");
		} else {
			for ( Iterator it = results.iterator(); it.hasNext(); ) {
			    QueryResult result = ( QueryResult )it.next();;
			    AssertedObject assertedObject=(AssertedObject)result.get( "assertedobj" );
				System.out.println("AssertedObject with value " + assertedObject.getValue());
			}		
		}
		logger.writeToDisk();	
	}
