Subject: [flexcoders] Re: Xml result / repeater weirdness (w Rails)
Solved my own problem & learned something today.
Turns out I needed to access via .children() like so
<mx:Repeater id="rptOrderLinesView"
dataProvider="{_selectedOrder.order_lines.children()}">
instead of
<mx:Repeater id="rptOrderLinesView"
dataProvider="{_selectedOrder.order_lines}">
Nothing to see here. Move on..
