DataGrid.selectedItem is set based on user interaction at runtime, so you
can't really set it the way you are trying. You could setup a binding there
in your code using BndUtils, but ugghh, ugly. I suggest you create a new
custom component component based on Canvas that has your DataGrid and
TextArea in it. I'd use MXML for this, its more descriptive eh? In this
component you could have
<TextArea text="{ myDG.selectedItem.someProperty}" ....
The skinny is that you don't try and 'call from the DG based on ID'. Either
use bindings as above in a custom component or use the event system.
HTH!
