please take this as interested and not critical. i was viewing the source: http://petshop.bivio.biz/src?s=View.items and i noticed these lines: ----- snip ---- ])->put( cellpadding => 2, cellspacing => 2, ), ----- snip ----- this looks like the presentation layer peeking through. the petshop site is obviously a demo, and therefore does not have the polished look of a professional site, which is very understandable. what i wonder is, could a professional web design team make a polished website without involving the programmers? what happens when a cell padding of 3 is more desirable for the design? it seems to me, that in all of the technologies i have looked at thus far, that attempt to separate the presentation layer from the model/view, the precision and flexibility needed to graphically communicate to the user is more difficult that the standard pagedesign approaches (dreamweaver and a little embperl or other embedded language thrown into the mix) . phrased another way, how does bivio or other mvc technology, let web artists design sites as beautiful as http://www.marthastewart.com or the even more beautiful http://www.genwax.com (cheap plug)? -- ___cliff [EMAIL PROTECTED]http://www.genwax.com/
