Since your linechart is inside a repeater, the member referenced by its
id (lineChart) is an array of line charts, not just a single reference
to a line chart. Since you're assigning an array as the dataProvider to
the repeater, it's trying to interpret that array as an array of legend
items, and failing.
It should be something like:
dataProvider="{lineChart[tabRepeater. currentIndex]}"

Subject: [flexcoders] Repeater and Chart Legend issue
I would to use the repeater class to create multiple instances
of a tab.Each tab displays the same chart with a different data
provider.Everything is working when I don't include a legend.
See source code below.However ,if I uncommented out the legend
I am getting the following example :
ReferenceError: Error #1069: Property marker not found on
mx.charts.LineChart and there is no default value.
at mx.charts::Legend/::addLegendItem()
Thank you for your help.
Regards-Claude
