Correction, 2 years, that will teach me for writing posts at 11 pm at night!

From what i ve researched so far, this is most likely the most complete Form module i ve seen in the YUI space. This should be promoted more...

Here is my usability feedback:

When I opened the first example, all the red backgrounds and exclamation marks screamed "You're wrong! You messed up! You suck!" Not a good first impression.

For complex fields like a phone number (in the formatter example), there is no indication what format is valid. (The comments above explaining the example do not count.) The error state simply remains red until I manage to guess what is expected. (As a side note, the phone number example doesn't work. When I enter "(123) 456-7890", the field is still red.)

After playing with the examples and being trained to expect the field to turn green immediately when valid input is entered, I tried pasting valid input into the field (using the Edit menu, not a keyboard shortcut), but the field remained red because it didn't notice the paste event. Only after I tabbed out of the field did it change to green.

In summary, I want a form that doesn't shout at me, that helps me figure out what I should enter (at least in the difficult cases), and that gently and patiently explains what I did wrong if I entered something invalid -- and only after I signal that I'm done, by pressing the submit button.
