Duplicate ids within separate div's DatePicker works great but places data in first no matter what

I have a reusable form which has a date text box in to which, when the form is initialized, I attach the datepicker. So to the first form I use jQuery to locate the text field like so $('#div1 #thedate') and to the second I attach the date picker in the same manner like: $('#div2 #thedate'). Note two different selectors. Date picker shows itself correctly on each text box however when I select a date in any one of the text boxes it places the date in the first one.

Now there is a ticket already on such an error and it was closed with the comment that you cannot have to fields within the same DOM but I question this because then we are concluding you cannot re use a form. I think this is a bug in datepicker.
