an applicative form. If you build a custom form, you have to declare a field
both in your form/view model and in your view, which is the kind of insecure
duplication we would like to avoid when possible.
You can already create custom form layouts with the monadic form creator.
Honestly I haven't used the new version at all or the old version for
anything that needs validation, so I am not sure if you can insert error
messages for fields.
Conditional validation logic is not really supported server side, let alone
client side. There are already several javascript generators for haskell. At
any rate it is probably a similar task to implementing reflection,
quotation, and javascript generation in F#, except that more needs to be
done at compile time.
We value your opinions. These are definitely features that I have needed on
occasion. We just have to think about how they best translate to haskell,
and how they fit into our limited time to make Yesod better.
