             Summary: CEP Operators in Rules failing to compile when getting PKG
                 Key: DROOLS-243
                 URL: https://issues.jboss.org/browse/DROOLS-243
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
    Affects Versions: 5.5.0.Final
            Reporter: Demian Calcaprina
            Assignee: Mark Proctor
            Priority: Critical


The issue is described in the following community post:
http://drools.46999.n3.nabble.com/Problem-with-PKG-from-guvnor-tc4025687.html

This code can reproduce it:
    	KnowledgeBaseConfiguration config = KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
    	config.setOption( EventProcessingOption.STREAM );
    	KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(config);
    	
    	KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory
				.newKnowledgeAgentConfiguration();

		aconf.setProperty("drools.agent.scanDirectories", "true");
		aconf.setProperty("drools.agent.scanResources", "true");
		aconf.setProperty("drools.agent.newInstance", "false");
        KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("MortgageAgent", kbase, aconf);
        Resource changeset = ResourceFactory.newClassPathResource(
                "cs.xml");
        kagent.applyChangeSet(changeset);
        KnowledgeBase kbase2 = kagent.getKnowledgeBase();

Creating a changeset that points to a binary package in guvnor, with a rules which uses the temporal operator. For example, somthing like this:
when 
        myfact: EventA( main > 21 ) over window:length (1) 
        myfact2 : EventA( main <= 21 , this before myfact ) over window:length (2) 

What is happening in that when it tries to compare the temporal distance, it will throw a NPE:
when 
        myfact: EventA( main > 21 ) over window:length (1) 
        myfact2 : EventA( main <= 21 , this before myfact ) over window:length (2)
