Is this a problem only when using LCDS?
Is this a Flex error or a coldfusion error?
If it is a Flex error it has got to be with the Datagrid control.
If it is a Coldfusion error, then, sorry, I can't help you but there should be
others around who can.

I realize this is an old thread I'm digging up, but I am running into the
same problem. I did the artists example from :
http://www.adobe.com/devnet/coldfusion/articles/data_app.html
The grid fills just fine but when I try to edit a cell I get:
Error: Unknown Property: 'constructor'
I looked around online and found others getting this error but no solutions.
Thanks,

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.

Subject: [flexcoders] Error: Unknown Property: 'constructor'. when using
LCDS
The fill method works great using RTMP and it fills a datagrid.
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.
Thanks,
Alexander
