[T5.3-beta-26] DateField Ajax JS errors

[Lenny Primak]

Just upgraded to beta-26, and started getting JavaScript errors when
submitting an AJAX form.

    <t:zone t:id="searchZone">
        <div t:type="button" cut="left">
            <t:beaneditform t:id="searchForm" object="search" zone="searchZone">
            </t:beaneditform>
        </div>
        </t:zone>

search object has a Date (hence the DateField bean)

I get the following errors starting sometime after beta-21 (it worked perfectly 
in beta-21)
