Hash is not defined (form validation)

[Viper]

Hi!
I'm using the validation for my form that loads though JForm. Some fields have a validate tag e.g. <field name="captcha" type="captcha" validate="captcha" />. In template I insert JHtml::_('behavior.formvalidation'); but when I press on submit button I get an error:

Error: ReferenceError: Hash is not defined
Source File: http://localhost/media/system/js/validate-uncompressed.js
Line: 155

What's wrong?

validator is using MooTools class Hash (http://mootools.net/docs/more/
Types/Hash) contained in MooTools More. Looks like there's a bug and
it's not being loaded along.

Quick fix is to force it using 'JHtml::_('behavior.framework', true);'

There's a patch for this bug:
