ExtendedDateChooser class is great solution for simple event calendar used in my flex project. You can find it if google for "Adding-Calendar-Event-Entries-to-the-Flex-DateChooser-Component"
with a link of updated solution in comments of the post. I posted files below.
Problem in that calendar is text events are missing when month is changed.
Is there updateCompleted event in Actionscript just like in dateChooser flex component? Like in:
<mx:DateChooser id="dc" updateCompleted="goThroughDateChooserCalendarLayoutAndSetEventsInCalendarAgain()"</mx>
When scroll event is added, which is
available in Actionscript, it gets
dispatched but after
updateDisplayList() is fired, so
didn't manage
to answer, why are
calendar events erased?
Any suggestions, what
to add in code, maybe override some function?
