Hi, I am trying to execute a simple DSL as below. Decisions is the bean class which I have imported in to Guvnor [when] IMRR action requested is in one of {acts} = Action(action in {acts}) [then] permitted =dec:Decisions dec.setDecision("Granted") Now I want the object for decision to be created and the value set in a single mapping. I tried the above code and got the error as below. [NamedParameterRule] Unable to build expression for 'consequence': java.lang.Class cannot be cast to org.mvel2.util.MethodStub ' System.out.println("Rule Fired From Guvnor"); dec: Decisions () dec.setDecision("Granted")' If I create the object in [when] clause it works fine. Any idea when this error would pop up?? and how to resolve this? Thanks, Barani -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Not-able-to-create-ob...
