[rules-users] How to write Drools rule basing on a changed property?

[kapokfly]

Yes, that is a Map base approach I am thinking. 

Now more questions:
 
global Map<Object, Object> oldObjectContext

WHEN
  $person: Person() 
  eval(((Person)oldObjectContext[$name]).jobTitle == $person.name)
THEN

Q1: without eval, the compiler will report error
Q2: without type cast, the compiler will also report error

Any suggestion how we can make it easier? 

Thanks...
