translator support outside of forms

[Dustin Frazier <ta...@frayzhe.net>]

I'm working on some generic form components, and I'm making a version that shows fields of 
a given object in read-only mode for users who don't have permission to edit.  I was 
hoping to go through my various components (TextField, DatePicker, Checkbox, etc.) and 
just change them to Insert components, leaving most or all of the parameters the same.

Unfortunately, it doesn't look like the Insert component supports the new translators. 
Are there plans to add support for this?  It seems like a very natural symmetry with 
respect to form input components.  Formatting is just one half of what translators do.

As I browse the source for the translator code that's in the Tap4 framework, very little 
of it actually has much to do with forms specifically; most if the code is generic 
parse/format code for different types.  This kind of general-purpose functionality would 
be *very* useful outside of the form context.

The Translator in Tapestry 4 can insert javascript into the page to
perform validation. So it's not that simple.

For your purpose, you may make an adaptor adapting a Translator into
a java.text.Format which can be specified as a parameter for the
Insert component.
