jquery ui - Datepicker returning uncaught typeError: undefined 'currentDay' -

i've been using jquery ui bootstrap , seem run problem haven't had before. i'm not sure has changed; i've tried setting different version of jquery , didn't update jquery ui in meanwhile. i'm not sure broke.

the error console when click on date in datepicker returns:

uncaught typeerror: cannot set property 'currentday' of undefined  

the code straightforward 1 expect datepicker:

$(".datepicker").datepicker({ dateformat: 'dd-mm-yy' });  

with following html:

<input type="text" class="datepicker" /> 

is bug should reported (since no other google matches turn up) or else i've missed?

i've found solution. after long time of debugging figured out there <div> had exact same id, lying higher input field. therefore script took first instance contained id , picked div instead of input field.

i removed/renamed div , worked fine again.
