<div>Good point Wolfgang - I linked to the wrong listener for tracking rule activations!</div>
<div><br>
</div>
<div>As Wolfgang alludes, I use object filters all the time for unit testing. It lets me create assertions about the objects that are in working memory. I find it very valuable when my rules are inserting new facts, rather than just modifying the fact I inserted.</div>
<div><br>
</div>
<div>btw - If your toString() method doesn't give you quite enough details about a fact, then the objectDetails(Object) method in the following will use reflection (via commons BeanUtils) to iterate through all the properties of an object and build a big string
from them. Which is a good reason to ensure that all your classes have decent toString() methods.</div>

<blockquote type="cite">Stephen has pointed you to a WorkingMemoryEventListener, and next to<br>
it there is also a TrackingAgendaEventListener. Callback methods<br>
beforeActivationFired and afterActivationFired bracket the execution<br>
of a rule's consequence, which, in combination with the WM events,<br>
will show you what a rule changes in WM.<br>
<br>
As to the facts participating in the firing of a rule: the Activation<br>
object of before/afterActivationFired lets you retrieve these Objects.<br>
(The list of FactHandle's may contain FactHandle objects that do not<br>
necessarily relate to Facts inserted into Working Memory.)<br>
<br>
If your Fact objects provide good toString() methods, putting this all<br>
together is a fairly simple task. Make sure to pick up Stephen's ideas<br>
about filtering - this may even be useful for unit testing.<br>

Or, do you want to understand more about the dynamic behavior as your<br>
