Yes. I recently needed to add a CSS class to an action button (in Zope 3.2 -- there's no time to port to 3.3/3.4 because Customers Demand Features). In the end I subclassed zope.formlib.form.Action and made render a regular method that did what I wanted it to do. > Leonardo, > you mentioned about overriding the renderer adapter. This could also solve > my problem, if possible. How to do that? Reading zope/formlib/namedtemplate.txt might help. You either have to use ZCML overrides, or subclass zope.formlib.form.Action (or attach marker interfaces to its instances, although that might not work given its copy-on-__get__ descriptorish behaviour). I must be missing something, because for the life of me I cannot see any point to zope.formlib.namedtemplate. What does it give you that subclassing and changing the render method/attribute doesn't?
