I'd recommend going through with the debugger too. Step into every function so that you can make sure you see what's going on, including stepping into the binding code. I can't remember what's going on off-hand, but Doug may be right that what you're seeing is a re-assignment to the same value, so binding doesn't fire, so nothing redraws.

Change the line: slicedRegionData.source = regionData; to: slicedRegionData.source = regionData.slice(); and you should find it now works. - Doug --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Robert Moss" <[EMAIL PROTECTED]> wrote: > > Sorry for bumping this, just hoping someone has an idea. > > Thanks, > Robert > > >>> "Robert Moss" <[EMAIL PROTECTED]> 12/8/2006 4:47 pm >>> > > In Adobe's dashboard sample app, http://www.adobe.com/devnet/flex/samples/dashboard/ <http://www.adobe.com/devnet/flex/samples/dashboard/> it assigns a charting component's dataProvider to an ArrayCollection's source (e.g. revenueData="{slicedRegionData.source}") In the regionChange () function it sets the array regionData and assigns it to slicedRegionData.source > > My question is, the delivered code > > slicedRegionData.source = regionData.slice(slider.values[0], slider.values[1] + 1); > Alert.show(ObjectUtil.toString(slicedRegionData.source)); > > and > > slicedRegionData.source = regionData; > Alert.show(ObjectUtil.toString(slicedRegionData.source)); > > Without the .slice, output the exact same data, but the region detail does not auto update without using the .slice code.
