Well, here's the actual error: Error: Error #1023: Stack overflow occurred. at flash.events::Event() at mx.events::FlexEvent()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\events\FlexEvent.as:1181] at mx.controls::NumericStepper/set data()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\controls\NumericStepper.as:629] at com.ItemRenderers::QtyRenderer/set data()[C:\Documents and Settings\LMacNeill\Flash Builder 4\QMS\src\com\ItemRenderers\QtyRenderer.mxml:9] at mx.controls::NumericStepper/get data()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\controls\NumericStepper.as:611] at com.ItemRenderers::QtyRenderer/set data()[C:\Documents and Settings\LMacNeill\Flash Builder 4\QMS\src\com\ItemRenderers\QtyRenderer.mxml:10] at mx.controls::NumericStepper/get data()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\controls\NumericStepper.as:611] at com.ItemRenderers::QtyRenderer/set data()[C:\Documents and Settings\LMacNeill\Flash Builder 4\QMS\src\com\ItemRenderers\QtyRenderer.mxml:10] (repeats the last two "at blah blah blah..." lines about 50 times)
If I reference 'data' anywhere in the set data function, I get the error. If I don't reference it, I don't get the error... But then I can't set the maximum for the Numeric Stepper... I'm thinking there might be a bug in Numeric Stepper, to be honest -- none of my other custom item renderers do this, and they're all structured EXACTLY the same way... L.
