Oops, I see that the operator still isn't quite right; you'll have to define<br>start and end of the interval:<br><br> this after[ 0s, 5s ] $event1<br><br>Just [5s] means "from 5s to infinity", which, after "not" is going to take a long time to decide :-)<br>
<br>Please check the documentation on temporal operators in the Drools Fusion manual.<br>-W<br><br><div class="gmail_quote">On 26 October 2010 08:55, david.bao <span dir="ltr"><<a href="mailto:david.lg.bao@gmail.com">david.lg.bao@gmail.com</a>></span> wrote:<br>

Now I understand I should use a "not" CE here. But following 4 code blocks<br>
return same result: no printing<br>
<br>
1.<br>
<div class="im">session.insert( event1 );<br>
clock.advanceTime( 3, TimeUnit.SECONDS );<br>
session.insert(event2);<br>
session.fireAllRules();<br>
<br>
</div>2.<br>
<div class="im">session.insert( event1 );<br>
clock.advanceTime( 3, TimeUnit.SECONDS );<br>
//session.insert(event2);<br>
session.fireAllRules();<br>
<br>
</div>3.<br>
<div class="im">session.insert( event1 );<br>
clock.advanceTime( 6, TimeUnit.SECONDS );<br>
session.insert(event2);<br>
session.fireAllRules();<br>
<br>
</div>4.<br>
<div class="im">session.insert( event1 );<br>
clock.advanceTime( 6, TimeUnit.SECONDS );<br>
//session.insert(event2);<br>
session.fireAllRules();<br>
<br>
</div>Thanks<br>
