[rules-users] Custom Operator - 5.4.0 works but nor not in 5.6.0.

Hello, I have written a drools custom operator called inlist. It takes two strings are parameters and works great in 5.4.0. I can do some thing like this. rule inList_1 dialect "mvel" when $cp3rRecord : Cp3rRecord (*primarySite*e inlist ("C500-C505") ) then System.out.println ("Fired inList_1"); end where primary site is a filed of the type Cp3rRecord and it works great in 5.4.0 There is a change in the API from 5.4.0 to 5.6.0 The Old evaluator is: /The new one (Per 5.6.0) is/ Note the third parameter! its is changed from Object to a Fact handle (*Please see lines 1) and 2)* ) When I extract the Object its returning me the FACT again and it blows off when I cast it to String. Any ideas please> I have been stuck on this for a day! I am getting the exception *cannot cast primarySite to a FactHnadle * Can some one throw some light on this one please? Thanks in advance!
