Datagrid discarding edit attempts?

I have a datagrid that is populated by the results of a remoting query(amfphp). The data displays just fine. However, whenever I try to edit any of the data, it changes back to the old value before the cellEdit event can even fire. Anyone have any ideas what could cause this? I can post code/fla file if necessary.

Thanks,

John

I found a solution. By binding the results of the query to a dataset and then binding the dataset to the datagrid, I could edit the data.
