I too like the post-redirect-get pattern as it i feel it provides a neater solution than tokens! It completely separates the actual Action from the next Actions preparation. If you take an action to have the following lifecycle: 1. Prepare data for action (eg read key from request and load a bean/actionform) 2. Display (eg show form for editing) 3. Process Submit (process submitted data) 4. Next action (begin cycle for next action) Now the code for struts actions without PRG tends to go 3,4,1,2 (although it can go 3,4,forward,1,2). With PRG you get two actions: one doing 1,2 (a) and another doing 3,4 (b) While i think this pattern makes more logical sense, i think that it is a bit odd to implement (a) in the same manner as (b). You can do it using a single action and use mapping.getParameter() to pick which part of the action you are on, or you can use two actions - both of which i dislike. So i think that a view controller could be useful. Someway of simplifying and decoupling (a) from (b) would be nice, and would save a lot of repetative code.
