Having the next code in a aui-form:

<aui:form>
	<aui:input type="checkbox" name="hello">
		<aui:validator name="required" />
	</aui:input>
	<aui:button type="submit" name="submit" />
</aui:form>

It's expected that the form will not be send onSubmit if the checkbox is not selected.

Currently if the user clicks the submit button a javascript error is throught and the form is submitted.

Note: The same validator works for other inputs, eg fort text.

Steps to reproduce:

1. deploy the attached auiform-portlet-6.2.0.1.war
2. add the AUI Form portlet to a page
3. click submit
