/**
* An Ajax.Updater as a button (that also submits the form and form values).
* <p>
* In order to use this, the form elements(i.e WOTextField, etc) need to have their name attribute bound to concrete values.
* The Prototype Ajax.Updater form is parametized using these names. WOElements won't correctly take form values otherwise.
* Also Prototype/WO integration requires the use of <button> rather than <input> WOSubmitButtons.
* </p><p>
* So set:
* <blockquote>er.extensions.foundation.ERXPatcher.DynamicElementsPatches.SubmitButton.useButtonTag=true</blockquote>
