BTW, I know what OOTB is, but how about "AFAIK"? Skip

It is great fun to play with YUI, Dojo and "Web 2.0 technology 57", but in terms of productivity my recommendation would be ZK (www.zkoss.org) or an equivalent "fully fledged" framework. > > We have been using the ZK framework with OFBiz for a while now (see http://docs.ofbiz.org/display/OFBIZ/ZK+Rich+Client+-+integration+tutorial ) .

This is because ZK takes care of the browser-server protocol in an optimised way. Apparently ZK3.0 will have more OOTB performance tweaks, however I have not tested this version yet. > > All I can say is, we would never go back to "traditional" web development, nor would we use "partial" toolsets like Dojo or prototype. Our productivity and UI usability improvements have been too significant. We would only consider moving "sideways" to another fully-fledged frontend framework like Flex or OpenLaszlo. Although as I argue here (http://www.theserverside.com/tt/articles/article.tss?l=ZKandAgile), so far we are very happy with ZK. > > cameron > > > > ___________________________________________________________ > Want ideas for reducing your carbon footprint?
