[flexcoders] Multiple initializers for property 'dataProvider'

[Raymond Brown]

Below is a snapshot of one of my components. However I am always getting an 
error on the Datagrid (id="cmdTable') and the error is:

Multiple initializers for property 'dataProvider'. (note: 'dataProvider' is the 
default property of  'mx.controls.DataGrid').

Does this mean you can't keep more than one datagrid or datagrid type in a file?

Here is my source -
