[rules-users] Does a drools fact have a handle?

Hello, in order to distinguish my fact instances I need them to have some sort of number/id. Before implementing it I realized that the KieSession is not working with my business instance references, but with FactHandles, so it occurs to me that there might be some standard id that is defined and populated by the Drools in runtime. So here is my question - Can a fact be identified by some sort of identifier after KieSession execution? May be if we get the FactHandles from it, or if we use the KieBase for that? Thanks in advance! Yoncho Yonchev.
