[seam-dev] Invalid field decorator

[Pete Muir]

Seems to me that s:decorate is more powerful than a facet, as it gave you the full templating power of facelets. If we could somehow automatically attach an s:decorate to each input field, I think that would be very nice.

BTW I think s:decorate still has more than JSF 2 right, does JSF 2 give you the #{required} boolean in EL from the required attribute on h:input? (It does give you the ability to query if there are validation errors and what messages are queued for a field IIRC).

Ideally, I would just like to have one facet on the page (with EL-switching between info and warn icons on a per-field basis). Of course, if we want half the field to follow another facet we need some configuring somewhere(tm)

Not doubting you, just would like to know the end-value you are trying to provide, since we already have UIInputContainer for building composite components that can be used to decorate input fields.
