2 textbox with same id, but in different container id, datepicker will update the wrong textbox

[wfsiew]

If there are 2 textboxes, but they are placed in 2 different container id, selecting the date in the second datepicker will always update the first textbox, but the second textbox won't be updated.

It's invalid to have two elements with the same id.
