Why couldn't the object itself know when the due date has passed? If you kept calling fireAllRules periodically in a thread, and had a rule like:<br><br>when<br> Order (dueDatePassed == true)<br>then<br> // do something
<br>end<br><br>Then you just need a isDueDatePassed method in the Order object, which itself compares the due date to the current time.<br><br><div><span class="gmail_quote">On 1/13/07, <b class="gmail_sendername">Faizan</b>
