If I replace the rule_a by the rule_b : (because an update should be better than an retract/insert I guess)</div><div><br></div><div><blockquote style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 40px; border-top-style: none; border-right-style: none; border-bottom-style: none; border-left-style: none; border-width: initial; border-color: initial; padding-top: 0px; padding-right: 0px; padding-bottom: 0px; padding-left: 0px; ">

</div><div><div>end</div></div><div><br></div></blockquote></div><div><div><br></div><div>> the result is bad : a message every 1 second. </div><div><br></div><div>It act as if the attibute message.internalEndDate wasn't updated in the drools engine. Could someone explain me if/why this behaviour is normal ?</div>
