The calendar view widget was jumping incorrectly to the next week

while selectiong the last day of the week.

The NumberPicker widget was getting into an inconsitent state when
reaching the end of the range (non wrapping selector wheel) and
the user touches the location of the hidden increment/decrement
button.
