reference 'dateField' object in javascript

Hi all,

I always thought you could attain a reference to the associated 
javascript object created by the 'Initializer' for tapestry components 
via the HTML element somehow?

In this case I am looking for the "Tapestry.DateField" javascript object 
for my field "selectedDateElem"

tml:
<t:datefield t:id="selectedDateElem" id="selectedDateElem" value="myDate" />

         alert($T("selectedDateElem")); // <-- [object Object]
         alert(typeof $T("selectedDateElem")); // <-- object
         alert($T("selectedDateElem").field); // <-- undefined
         alert($T("selectedDateElem").dateField); // <-- undefined
         alert($T("selectedDateElem").datePicker); // <-- undefined

         alert($("selectedDateElem")); // <-- [object HTMLInputElement]
         alert(typeof $("selectedDateElem")); // <-- object
         alert($T("selectedDateElem").field); // <-- undefined
         alert($("selectedDateElem").dateField); // <-- undefined
         alert($("selectedDateElem").datePicker); // <-- undefined

Can someone explain what I'm missing?

Thanks.

Re: reference 'dateField' object in javascript

Posted by Paul Stanton <pa...@mapshed.com.au>.
 From further debugging, it seems the object is 'lost in the ether' ie, 
there is no reference attached to it when it is created...

Tapestry.Initializer.dateField = function(spec) {
     new Tapestry.DateField(spec);
}

It would be very easy to solve this via:

Tapestry.Initializer.dateField = function(spec) {
     $T(spec.field).dateField = new Tapestry.DateField(spec);
}

I'm not sure why this isn't the standard for all tapestry-created 
javascript objects?

Probably the "they'll never need that" oversight?

cheers, p.
