[rules-users] Cant seem to fire a dynamically added rule

[samirsss]

I tried using the jars from the 4.0.x branch after building them and that
still doesnt seem to change the outcome. I see that the package builder has
the rule added to it and the count of the rules from it is incremented.

public void testDynamicRules()
  {
	  //Create a rule dynamically and check if it fired from log statements
	  RuleBase ruleBase = wm.getRuleBase();
	  Package[] pkg = ruleBase.getPackages();
	  if(pkg[0] != null)
	  {
		  logger.warn("Package size before adding the rule :
"+pkg[0].getRules().length);
		  //Building a new package
		  final PackageDescr packageDescr = new PackageDescr(pkg[0].getName() );
		  //Building ruleDescriptor
		  RuleDescr ruleDescr = null;
		  String consequence = "\t\t mediator.addedNewRule();\n";
	      ruleDescr = new RuleDescr( "Added new Rule");
	      AndDescr lhs = new AndDescr();
	      ruleDescr.setLhs( lhs );
	      
	      final PatternDescr pattern = new PatternDescr( "ApplicationEvent",
//.class.getName(),
	              "newAppEvent");
	      lhs.addDescr( pattern );

	      final FieldConstraintDescr insertedValue = new FieldConstraintDescr(
"inserted" );
	      final LiteralRestrictionDescr insertedFieldRes = new
LiteralRestrictionDescr("==", "false",
LiteralRestrictionDescr.TYPE_BOOLEAN);
	      insertedValue.addRestriction(insertedFieldRes);
	      pattern.addConstraint(insertedValue);
	      final LiteralRestrictionDescr restrictionMessage = new
LiteralRestrictionDescr("==", "Test2", LiteralRestrictionDescr.TYPE_STRING);
	      final FieldConstraintDescr returnValue = new FieldConstraintDescr(
"messageId" );
	      returnValue.addRestriction(restrictionMessage);
	      
	      pattern.addConstraint(returnValue);
	      
	      ruleDescr.setConsequence( consequence );
	      List attributes = new ArrayList<AttributeDescr>();
	      attributes.add(new AttributeDescr("salience", "101"));
	      ruleDescr.addAttribute( new AttributeDescr("dialect", "java") );
	      ruleDescr.setAttributes(attributes);

	      Package defaultPackage = pkg[0];
	      PackageBuilderConfiguration conf = new PackageBuilderConfiguration();
	      PackageBuilder builder = new PackageBuilder( defaultPackage, conf );
	     
	       packageDescr.addRule( ruleDescr );
	       builder.addPackage(packageDescr);
	      
	       DrlDumper drlDumper = new DrlDumper();
	       
	       logger.warn("Dumping Package Descriptor for all rules: "+
drlDumper.dump(packageDescr));
	       int errors = builder.getErrors().getErrors().length;
	       if(errors > 0)
	       {
	    	   //TODO remove the recently added rule or reload all the rules from
the DRL file
	    	   logger.warn("Error while adding a rule");
	    	   
	       }
	       else
	       {
	    	   Rule newRule = builder.getPackage().getRule(ruleDescr.getName());
			   logger.warn("Package after adding the rule : "+newRule.toString()+":
contains: "+pkg[0].getRules().length+" rules");
	       }
	  }
	  else
	  {
		  logger.warn("Error getting default package for adding rules");
	  }
	  
  }

I am trying to figure out if I am doing something wrong or its an issue with
Drools.
