Looks good. 2 additional questions:
- cross-browser compatibility? Tested it on the incubator, looks good (apart

I used the default CSS provided by livevalidation. Of course, we can
tweak that.
This could be quite handy to use on plenty of
other forms in XWiki. How
easy
will it be to add to any of our numerous
object-creation input fields
(like
create page, create blog post, new applications,
basically any field we
could think of)?
Easy. For example to add both presence and emai validation to a
field,
you add the following in a JSX object,
var emailV = new LiveValidation( "register_email" , { validMessage:
"OK.", wait: 500} ); // register_email is the id of the field to validate.
emailV.add( Validate.Presence, { failureMessage: "Field is mandatory"
} );
emailV.add( Validate.Email, { failureMessage: "Should be a valid
email" } );
I said, if we want we can also write basic CSS-based set of rules, to
allow doing validation using :
<input class="validate-email" .... />
We just need to write a piece of JS that on loading will lookup for such
classes and do the wiring. This would be for non-developers.
- internationalization?
That's not an issue, we can use $msg.get in JSX

Dear
devs,
I propose we bundle the "validation as you type" livevalidation.js
library [1] in XWiki, and use it to improve user experience on several
forms in XWiki Enterprise (I can think of registration form, export wiki
form, page creation panel, etc.) There are several advantages I see in
livevalidation compared to the other libraries I took a glance at :
* It's small (12Kb minified)
* It does not have any dependency (but there is version based on
prototype available, too)
* It is not intrusive. No need to modify the html structure or to add
css classes to input fields to add validation.
* It has an nice feature which allows you to precise the delay after
which the validation should occur once the user stopped typing
If you want to see it "live" in XWiki, I added some basic presence,
password confirm and email validation on the register form on
http://incubator.myxwiki.org
CSS-class based validation seems to be in some sort of fashion, though
I'm personally not very convince we can express all our validation using
only class names (sounds intricate to do cross-field validation for
example, or to validate against a custom regular expression), and for us
it is not really an option right now, since we would need to make
modifications in the core of XWiki for object fields displayer to add
the proper class names to the inputs when calling APIs like $doc.display
(or do it in javascript, but the CSS-based becomes pointless then).
Last, if we really want class based validation, I believe building it
with prototype and livevalidation would be very easy.
Here are the other alternative I looked at rapidly:
* JS-Validate [2] 67 Kb, requires prototype + scriptaculous, CSS-based ,
licence?
* really-easy-field-validation [3] requires prototype, CSS + JS based,
MIT licence
* wForms [4] 81Kb minified, CSS-based , LGPL
Better alternatives you would see?
Otherwise, my +1 for livevalidation,
Regards,
Jerome.
