Small bug with - datepicker for dates range

[EGrozdev]

After focusing 'from'* input element

1. Select 'from' date with date picker
2. Then manually delete 'from' content in input

At this stage date picker is in open status and 'from' date can be picked

3. Pick the date -> nothing happens as 'on change' event may be overrides ui behavior
4. If you pick the 'from' date again it will be appeared in 'to' date
   • it could be either 'from' or 'till' - both has above mentioned bug.

I personally solve the issue by unfocus input element and hiding date picker, but there should be default functionality I guess.

My solution (in CoffeeScript):

$("#date_from, #date_till").on 'keyup', (e) ->
   if e.which == 46 and this.value.length == 0
      this.blur()
      $("#" + this.id).datepicker('hide')
