Me too. The concept is jut too nice to be thrown away.
IMHO this DataView "language" is the closest to the most practical and efficient
Form/UI Domain Specific "Language", I've seen so far.

This is fantastic. IMHO exactly what's needed. Based on the generic
remaining part one could than implement:
dataview.click package
dataview.tapestry package, etc.

Would be useful to have these too:
  - "pattern" for pattern oriented fields
  - "rows" and "cols" for (J)TextAreas or other rich text areas (JEditorPane, etc.)

The validation (for the Swing implementation of DataView), could be better served IMHO by
this
framework:

(instead of an "own" implementation)

RadioGroup is in the same situation.

Also there could be support for I18N since this is done easily with Swing and also with most
of the webframeowrks.
