Hmm, sounds like you are doing something fairly
similar to what I'm doing with Trails. Check it out
at trails.dev.java.net. In Trails, I solve the
problem of needing to dynamically decide how to
render a property by using the Tapestry recommended
approach, Block components. I have Blocks for each
editor (string, date, number, etc) and choose which
Block to render by the type of the property (or other
metadata).
