[flexcoders] Data Binding warning -- PHP, Weborb for PHP

[jason_panko]

I have been following the "simple_weborb_php.mxml" example from The
Midnight Coders website and have run into a warning:

Data binding will not be able to detect assignments to "dataProvider1".

Now I started with the simple_weborb_php.mxml file and proceeded to
add a second datagrid. My first datagrid connected to my database and
posted the results. However, if I ignore the Flex Builder warning and
try to run, nothing populates to my second datagrid and I get no errors. 

Any suggestions?
