[Zope] How does dtml-sqlgroup really work?

[Jorge O. Martinez]

Hi:

I can see that now. That's unfortunate, sqltest would be a lot more useful if 
it was 'smart enough' to do nothing if the var is not set or does not exist 
(the power of dtml-if + the power of sqltest combined I guess).

Thanks for your feedback

Regards,

Jorge M.
