Subject Re: how to use a checkbox with DatabaseUpdateAction
Date Thu, 25 Jul 2002 13:27:37 GMT
Thanks Christian. I'll look into this. My fallback plan is to write a 
logicsheet in XSLT/ESQL to do the same as the DB actions but at a higher 
level. What I'm trying to end up with is an XForm-like way of writing 
(simple model) forms but without having to write any java. For many 
simple applications, this is all lots of people would need (I think).
