Flash Builder: How to verify if the date has been selected in datechooser component?

Question

I am trying to verify if the users select a date in my date chooser spark componet. I tried:

if(dateChooserBegin.selectedDate){
..........
}

I will get a run time null object error. I was wondering if anyone here know to do this. Thanks for the help.

Answer 1

You will probably need to extract the date from the CalendarLayoutChangeEvent event object that is raised on choosing a particular date. See the example on Flex livedocs (particularly the useDate event handler.

Answer 2

Best way I can think of is adding on to what dirkgently said. Set on onChange event on the dateChooser to change a global boolean value to true. Then in your if() check if the boolean is true. Only other method I can think of to ensure that ANY date is set is to use a selectedDate on the dateChooser itself, forcing a default date in there.
