Hello,
I'm re-posting this because I am pretty sure it is a bug, and I was
hoping one of the Flex engineers could confirm that it has been noted
(if not tested).
I'm getting really sporatic responses from a listener to the
ChartMouseEvent.MOUSE_OVER_DATA
By "sporatic" I mean that the events only fire if the mouse is going
one direction (left to right on the non-stacked one I believe)
and the event doesn't fire at all when entering a chart item from one
side or the other; Only when crossing from one item to another.
Note it wasn't this way in the alpha. Only significant differences on
my part is the use of XMLListCollecitons as data providers.
see the sample app below. It should reproduce the defect.
Thanks,
Thunder
