As a practical matter, I think the best test is always going to be: What happens when the suits want this done outside of a Web application?
If sorting is done on the model tier, then it is reusable in a Swing application, a PDF, a XLST document, a Velocity template, and even an email. In end, whereever you do it is going to require a comparable amount of work. The question is whether the work is going to be resuable or not. -- Ted Husted, Husted dot Com, Fairport NY US -- Developing Java Web Applications with Struts -- Tel: +1 585 737-3463 -- Web: http://husted.com/about/services Michael Marrotte wrote: > > Andrej; > > I've seen this lightly debated, before - that is, whether or not sorting > should be in the Model or the View.
