<br> Martin,<br><br> I'm not sure I completely understood your problem. An easier way (although not necessarily faster way) of doing it is:<br><br>when<br> A( $session : oA.session )<br> B( oB.session == $session )
<br>then<br><br> Hope it helps.<br><br> Edson<br><br><div><span class="gmail_quote">2007/12/24, Martin Book <<a href="mailto:m.book@web.de">m.book@web.de</a>>:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
