[flexcoders] Populate one Datagrid from another

[fusioninteractive]

I have two Datagrids in my flex app.  The first one shows a list of
states and the total number of times someone from that state has rated
a plant on my site.  I want the other grid to show the average ratings
of the plants people from a specific state have voted on.  I am using
ColdFusion 8 and Remote Objects.  So the question is how do I bind the
second datagrid to the state selected on the first?

Thanks,

Jason
