I found this.
"Using ColdFusion in concert with the DataGrid component is a great way to
introduce the merits of the facade pattern. Most CF developers are quite
familiar working with recordsets in CF. While it is possible to pass
recordsets from ColdFusion to Flex, Flex is much happier working with arrays
of structures. First, the performance of arrays of structures is far
superior to recordsets in the Flash player. Second, while Flash Remoting can
accept a recordset from CF and even use it as a dataprovider for a DataGrid,
you will receive an error ("Unsupported type found in stream") upon trying
to pass the same structure back to ColdFusion via Flash Remoting. "

But not sure I understand how to convert this from flash to cfform flash
action script. It seems that you have to convert the query to an array (did
that with the udf they suggest) and then assign the results to a new object
in your action script something like var employeelist = {};
And then use the new object holding the results to the grid like
gridname.dataProvider = employeelist;
But this does not work. It gives me an empty grid.
