The problem we have is that rules will be code by business user. As a developer
I don’t mind putting null check on every rule. But for business user its
unacceptable for checking null for the same attribute in around 50 rules. <br>
<br>
<st1:place>Shannon</st1:place>, can you please elaborate more about your
solution or if possible post some simple code?<b><span style="font-size: 10pt; font-family: "Courier New"; color: rgb(150, 0, 0);"><o:p></o:p></span></b></p>
