after re-reading that message I find it a little to ... mixed up.
one idea was that you could use a ShowRangeHandlers<Date> that you'll
add it to your DatePicker object,
on the onShowRange() method you'll need to take the date list between
the start and the end of the range, and for the dates that are <= your
lastDisabledDate do a call of
datepicker.setTransientEnabledOnDates(false,date);
or you could add the disabled dates to a list and call
datepicker.setTransientEnabledOnDates(false,disabledDateList); //
this will call the first method so will be no gain
this approach is time consuming it's a heavy load when there are many
days to disable
a second idea:
the default constructor DatePicker() calls the following constructor
DatePicker(MonthSelector monthSelector, CalendarView view,
CalendarModel model)
with the following arguments
new DefaultMonthSelector(), new DefaultCalendarView(), new
CalendarModel()
the CalendarView (DefaultCalendarView) is the class that takes care of
the dates isEnable()
because you don't have access to that second constructor you'll have
to make your own DatePicker that extends DatePicker so that you could
access it, and instead of using the DefaultCalendarView use your own
class made from the code of this one and change in the inner class
CellGrid the method isEnabled() so that it'll make the check if the
date is < lastDisabledDate
lastDisabledDate would be set by a method of your custom DatePicker to
your custom CalendarView.
this is a more elegant approach (I think) and also could be used to
disable specific dates (a list of dates), or a specific dayOfWeek
good luck
