<p class="MsoPlainText"><span style=font-family:"Calibri","sans-serif";color:#1F497D>I mean, yes, what you suggest here works (and it works perfectly). But, for such an important and common user concern, we currently face a lot of "Drools .DRL keystroke
labor" to get us completely where we need to be wrt to coding this tactic completely.<o:p></o:p></span></p>

<p class="MsoPlainText"><span style=font-family:"Calibri","sans-serif";color:#1F497D>Does your Intellifest white paper (today is the day? HOORAY!) comment at all on strategies to achieve this pattern in .DRL code? It would be way cool if the framework
itself liberated us with a “just add water and out comes the .DRL code you want” capability. Such a capability would deliver to users a full answer wrt to our “when do rules fail to fire?” accounting needs.<o:p></o:p></span></p>
