Re: [flexcoders] null parent for ChartLabel
That's the thing: nothing especially complicated going on. We have custom axes and custom labelFunctions, but we're using the stock AxisRenderer. We re-parent the Chart during this layout change, but that's it (we certainly don't re-parent the labels manually). Perhaps I'll try to see if I can get a simple re-parenting test case to repro this, and I'll file a bug with that.

Re: [flexcoders] null parent for ChartLabel
I extended ChartLabel, overrode updateDisplayList() to do what you suggested, Tom, and set the titleRenderer on the AxisRenderer, and that seems to work around the issue. I still could be doing something wrong, but this looks like a framework issue. I'll check the latest sdk version and file a ticket if necessary.
