DataProvider syntax error -why cant 2 components have the same dataProvider

Question

Hi,
I am getting the following error:
Multiple Initializers for property 'dataProvider' (note:
'dataProvider' is the default property of
mx.controls.TitleList').
setup
i have two components one that is a lineChart the other is a
titleList. for each I have identified the dataProvider property as
the same arrayCollection (dataPoints) so my code looks like:
<mx:LineChart
id="linechart"
dataProvider="{ dataPoints }" .... other properties>
for both components. I had this same error when i tried to
add a legend component yesterday so it is not limited to just these
two components. I tried instantiating a variable as a type
dataProvider, so that it was not being instantiated twice, but no
such primitive type was available via the auto-complete code
function. I am not sure what else to try. Thanks,
Jed

Greg,
Thanks again, I figured out the problem. In the mxml I was
using the category axis tag without having a parent horizontal axis
tag. So for others here is how a chart needs to be structured.
correct syntax:
<LineChart id="linechart1" dataProvider=" {
myArrayCollection } ">
<mx:horizontalAxis>
<!--use the category axis tag to tell the chart what value
in your array collection you want to use for the x axis-->
<mx:CategoryAxis categoryField="x"/>
</mx:horizontalAxis>
<mx:series>
<!--Use the line series within a series tag to tell the
LineChart which y field it should use to draw the line-->
<mx:LineSeries id="yourFirstYvalues" yField="y"/>
</mx:series>
</mx:LineChart>
<mx:Legend dataProvider = "linechart1" />
