[flexcoders] Error #1010: A term is undefined and has no properties -- RTE with Datagrid

[jmorpher03]

Hi,

I have a DataGrid with a custom item renderer (containing a Checkbox 
and Label). As soon as the data is populated via an XML returned by 
the server, the following error comes up: 

TypeError: Error #1010: A term is undefined and has no properties.

I saw in a couple posts that this is a bug, if yes, is this fixed ?
