In the forum post "How to make jquery autocomplete to work for a contenteditable DIV instead of just INPUT, TEXTAREA fields." we see how to get autocomplete working on a contenteditable div element, however combined with datepicker the datepicker simply does not populate the input field.
As you can see in this jsFiddle demo: http://jsfiddle.net/xvnaA/
Anyone have any wise ideas on how to fix this?
