Datepicker Bug

The datepicker works great except when I try to put it in a data grid
(HTML table with numerous <tr>'s). I've given every row element a
unique id, but that didn't seem to fix the problem. I think I've
found two bugs. One of them is when I use jQuery to try to clone a
row (<tr>) I get an error. The autocomplete works great on the jQuery
clone, but not the datepicker. Below is the information. Please let
me know if I'm just missing something, there is a fix for this, or if
it would be helpful for me to provide additional info.
In ui.datepicker.js
.clone(true);        //after using jQuery to clone a table row (<tr>).
var inst = $.datepicker._getInst(input);        //this function call returns
undefined when clicking on the new row's input box tied to the
datepicker.
/* Notes
    input.outerHTML = <INPUT class="GridDate hasDatepicker"
id=Eff_Start_dt2 style="WIDTH: 70px" jQuery1231283246537="190">
*/
