I think we might be able to come up with a heuristic for choosing between the two patterns (this might be a mini pattern language, if refined): - For "simple" forms, which redisplay themselves even after a successful POST, and which do not redirect, prefer a template-driven version, and make the form self-posting; in ZCML, use <browser:page> with the 'template' attribute). The classic 'document_edit' form fits this bill, I think. - If you have to add logic to the template to cope with possible redirects, then publish a method of the view, and have the view redirect or return a template; in ZCML, use <browser:page> with the 'attribute' variant. "Add" forms fit this pattern, as well as the folder_contents stuff that Yuppie has done. - For a set of inter-related pages sharing common view logic, you may end up mixing and matching -- the ':method' bit on submit button names is a way to get "off" the original template when needed. ZCML for this case may either be a mixture of the 'template' and 'attribute' variants of <browser:page>, or else <brower:view> with several <page> subdirectives. How does that sound?
