[rules-users] Traversing the Rete Network

Hello, I am trying to find out if and why a rule is not activated/fired when asserting a piece of data. At the moment I am using JBoss AOP to pointcut the method EntryPointNode.assertObject(), and from there I run an algorithm to walk to "every" node in the rete network. My question is how can I be sure that I have indeed accessed every node in the network? Thanks for your help. Regards, Peter
