Hi All,<div><br></div><div>I don't know whether I have encountered a strange problem or my understanding of drools is wrong.</div><div><br></div><div>I have 3 rules out of which two are dependent. Between the dependent ones one rule makes the other rule eligible to fire but I don't know why the dependent rule is not firing. Below are the rules I have written.</div>

I think we can use <span class="Apple-style-span" style="font-weight: bold;"><span class="Apple-style-span" style="color: rgb(204, 0, 0);">update </span></span>in <span class="Apple-style-span" style="color: rgb(255, 0, 0); font-weight: bold; ">AlcoholConsumptionClassRule </span>but I think if we have to manage those dependencies it will be more error prone and the results are might be more inconsistent. </div>
<div><br></div><div>I have tested it Using RETEOO in drools 3.x and 4.x which yields me the same results. But when I used LEAPS algorithm then i even got the dependent rule i.e <span class="Apple-style-span" style="color: rgb(255, 0, 0); font-weight: bold; ">UnderwritingFactorRule </span><span class="Apple-style-span" style="color: rgb(255, 0, 0); "> </span>rule also fired<span class="Apple-style-span" style="font-weight: bold; ">.</span></div>
