[rules-users] org.drools.runtime.rule.ConsequenceException: [Error: unable to access property (null parent): add] [Near : {... Unknown ....}] ^ [Line: 1, Column: 0]

Ashish,
My guess is that you are navigating properties and the something along  
the way is null.
Eg object.prop1.prop2 where prop1 is null. If prop1 can be null you  
have to check for nullness first, ie.
object.prop1!=null, object.prop1.prop2....
