The hairy catchword in the post is &quot;only&quot;.<br><br>Most of the time, it&#39;s best to design the conditions so that only one rule will reach the agenda.<br><br>If this is too circumstantial, salience might be used to let the &quot;special&quot; case fire before the &quot;general&quot; case; but then something must be done to remove the activation of the latter. You can, for instance, retract the (a) contributing fact. Or mark it and include &quot;not marked&quot; in all conditions. Or...  <br>

<br>
I am new to all drools...<br>
How can I &#39;mutex&#39; in drools? Or could you suggest a better concept for that?<br>
(i mean, when two rules would fire : rule1 and rule2 in agenda<br>
the mutex is checked and             : mutex for this case is defined, rule1<br>
= higher, rule2 = lower prio<br>
only the one rule with higher priority will be executed)<br>
<br>
<br>
Cheers. Please let me know if my question is understandable...<br>
