<br>Hi Smitha, <br><br>They way I understand, in the then clause you would like to call a static function from some class. So, then you can add that to the import and access it directly. It does not have to be global. However, if for some reason you do need to add it as a global,, let me know.
<br><br>send that when part of the rule again. <br><br>-Krishnan. <br><br><div><span class="gmail_quote">On 6/18/07, <b class="gmail_sendername">Smitha Bhat</b> <<a href="mailto:bhat_smitha@yahoo.com">bhat_smitha@yahoo.com

</div> <div> </div> <div>When I debug the 'when' piece, I see that the method to check the name is being called, but tfter that, the global util's class method is not called. Any pointers would be helpful.</div>
