Not bad. Little more complex than I was thinking- Most JS libs worth their salt have in-line editing type deals (where you're in a "view" and you click on a field, say the "First Name" field, and it becomes a text-box so that you can edit content)- aside from the first insert, how often is /every/ field changed? That's the beauty of AJAX, or at least part of it-- you only need to send the data you need. So basically, you handle every field edit (aside from the first insert) individually. You can use nice little JS stuff that instantly tells someone if they've entered a bad value (using the server, mind- not client JS code) and whatnot. Since you're doing everything "piecemeal" soto speak, adding a "logger" is a piece of cake. It's already broken down into little bits, see. That's basically what I was thinking. AJAX is FAR from a "display" technology*. Far far far. But I do love my fancy fades and whatnot. :-) *this is one of my main issues with MVC "design"-- the UI can have a HUGE effect on the app-- huge! Hard to split everything into dispirit parts, ya know? Bah. Now that was a poor expression of whatever I meant. =-) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| ColdFusion MX7 and Flex 2 Build sales & marketing dashboard RIAâs for your business.
