I'm having problems catching events within an item renderer.
I have a custom radio button group renderer class which
dispatches an Event.CHANGE event when a radio button within the
group has changed.
I'm trying to add an action listener to the component which
uses the renderer but am unsure how to do it. Attached is the code
which adds a new instance of the renderer class to the component's
item renderer (it's part of a data grid). I've tried adding an
event listener to the base component but that doesn't pick up the
event when it fires. I can't add the listener to the item renderer
and the DataGridColumn object only accepts either Event.ACTIVATE or
