<div><br></div><div>I don't believe there is a public API (or any) that could be used to trace which RETE nodes matched for a given rule's definition and hence which did not for you to identify unmatched patterns. Someone correct me if I am wrong.</div>
<div><br></div><div>Of the top of my head, you could possibly achieve what you are looking for by structuring your rules differently; having each pattern in a separate rule and tracking accumulated rule activations yourself. Not nice, not helpful if rules are authored by anybody other than a techy, but it might just work....</div>

<br>
Hope you are doing good.<br>
<br>
I saw your post regarding AgendaEventlisterner.<br>
<br>
I got your zip file, the code is working fine.<br>
<br>
But the activationcancellation method is not getting invoked. I need to identify which condition in the rule failed.<br>
<br>
Can you pls help me.<br>
<br>
