mx:Datechooser Flex 3 multipleselection multiple select dates
Never found a straight-forward example of how to set multiple date ranges on a
datechooser component.
The critical part is getting your head round the basics which means cutting away
all the chaff and fancy stuff.
This is the bare-bones nitty gritty. It doesn’t get simpler than this.
It’ll do for me! (unless someone sees some bug or other!)
