Ely,
Interestingly, I went and modified one of the examples from the
ChartExplorer to send to reproduce and send to you. It's labelRotation was
set to 90, and the error wouldn't reproduce. So I changed it to 75 (which
is what I had my production chart set to) and sure enough, error. I didn't
try everything > 0 and < 90, but i'd assume that's where the error
occurs... Below is a reproducable app... just drag the divider up until
the label's disappear on the chart.
Thanks

Hi
Brendan. I think I actually just fixed this bug in the mainline a few
days ago. If you have a simple reproducable file you could send me, I can
verify it.
Thanks,
Ely.
Hi,
Came across something today, which I'm guessing should be filed
as a
bug...
If you are using an AxisRenderer on a chart, and resize
the Chart
instance to the point that the labels disappear, you get the
following
Cannot access a property or method of a null object reference.at
mx.charts::AxisRenderer/adjustGutters()[C:\dev\beta3\sdk\frameworks\mx\charts\AxisRenderer.as:1182]
