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

             Summary: Drools plugin Rete Tree viewer does not work with timer and || operator.
                 Key: DROOLS-320
                 URL: https://issues.jboss.org/browse/DROOLS-320
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 6.0.0.CR5
         Environment: Mac OS-X 10.9, JBoss Developer Studio 7, Oracle Hotspot 1.7.0_45, Drools-jBPM Eclipse plugin 6.0.0.CR5
            Reporter: Duncan Doyle
            Assignee: Mark Proctor


See this example project: https://github.com/DuncanDoyle/DroolsReteViewer , which is based on the Drools Eclipse sample project.

The 'src/main/resources/rules/Sample.drl' is a valid DRL file, but it cannot be opened in the Rete Tree because of:
- the 'timer (int: 10s)' definition in rule "GoodBye-Timer". This gives the error:
Rete Tree Build Error!
Reason:
org.drools.core.RuntimeDroolsException:
java.lang.reflect.InvocationTargetException: [Rete(0)]

- the '||' operator in the rule "Hello World-Or". This gives the error:
Rete Tree Build Error!
Reason:
java.lang.NullPointerException: null

This forces us to change our rule definition files to be able to inspect the Rete Tree (which we require to analyse the tree for possible optimizations).
