Check for the non-existence of a fact specific to the rule on the LHS. When the rule fires, assert the fact to ensure it never fires again. For example<br><br>rule "Foo"<br> when<br> not Fired(rule == "foo")<br>
....<br> then<br> insert(new Fired("foo"));<br> ...<br>end<br><br><div class="gmail_quote">On Wed, Apr 15, 2009 at 11:53 AM, Brody bach <span dir="ltr"><<a href="mailto:brodybach@yahoo.com">brodybach@yahoo.com</a>></span> wrote:<br>

Hi all,<br>
<br>
Is there any way how I make a rule only executed once( i.e. if it has fired<br>
once, no other facts should be checked against it)<br>
<br>
Thanks for any hints<br>
Regards<br>
Brody<br>
