Do you know ActionScript your objects from CF land are getting converted to? Typically they come across as Objects unless you are mapping a strong type in which case you need to mark those classes with [Managed]. This appears to be something which does not extend Object - like maybe XML?
If you can't tell, adding <mx:TraceTarget/> in MXML and using the debug player you can get a flashlog.txt which should have that information (feel free to send that to me directly offlist). We use the constructor property in some cases to determine which class we are dealing with but there are other ways we could do that.

When i make the datagrid editable and change a value, It returns this error: Error: Unknown Property: 'constructor'. The backend is connected with coldfusion CFCs. Again the fill method works great.
