double div datepicker when fired domready

[pelikanek]

Hello, thanks for great datepicker! I found some error when I must use this code after ajax request:

window.fireEvent('domready');

It created another div with class="datepicker", so many div with this class do some wacky result. I fix it with this code (I clear every your hidden datepickers before running Picker class):

$$('.datepicker').each(function(el) {  
  if (el.getProperty('aria-hidden') != null) el.destroy();
});

and then I use normal code...

new Picker.Date.Range($$('.datepicker_datum_range'), {
    timePicker: false,
    columns: 3,
    positionOffset: {x: 5, y: 0}
});

@pelikanek can you reproduce your problem in a jsFiddle?
On a fast look at the source I didn't find any domready event handler that could be listening....
