it will at some point.

Thanks Matt...
could you provide an example of how to specify the update of the data?
I assume that there would be a bit of code inside the mouseOut handler (or
wherever I want) to push the data back into the XML model.
Figure I have this TextInput bound to the xml (e4x) ...
<mx:TextInput id="price" text="[EMAIL PROTECTED]"
mouseOut=" what goes here? " >
This is a simple case, but the solution should also elegantly apply to
automatically generated / replicated list items... and also executable by any
arbitrary code easily....
so some distant script could say price.model.update() or something
to push the current price.text back into the xml where it came from...

The automatic update of the data itself will be available in

The cell renderer APIs may help show you what can be done in
Flex 2 as well.

This will be handled in the Flex2 data services.
More importantly is
that the changes (inserted, added and deleted
buffers) will be
marshalled to the server as needed and can be
bound to a persistence
adapter (say Hibernate) to even manage updating
the data store with
the changes.
That's where the real power comes in.
