I ran into this issue myself and found two things that cause "inst is
undefined". Both situations typically result from using the jquery
clone() method either directly or as a side effect of some jquery
library:
1. If you initialize datepicker on an element that already has class
"hasDatepicker", datepicker will think the initialization has already
happened.
2. If you initialize datepicker on an element that has the same id as
another element on the page, datepicker is prone to grab the
uninitialized element by id while operating on the initialized
element.
Hope that helps,
Nick
