Problem with datePicker shortcuts

Problem with datePicker shortcuts

Hi,
This is a weird bug and will require some testing of you to find out what is really happening. I created a datepicker that shows on keydown (arrow down)
  • If a date is allready set when you enter the date field and you click arrow down (or open the datepickier clicking the button) and select a new date (using shortcuts), the date is not changed.
  • If you change to a date in another month, the date is always changed.
  • Sometimes if a date is set you can change it the first time, but not the second time.
  • Other scenarios?
As you will see, selecting a new date does more often not work than work.

Thanks for your patient.

PD: I have a file attach a file in order to reproduce easily but i am sure you will can reproduce in your applications.
