Howard M. Lewis Ship closed TAPESTRY-1998.
------------------------------------------

       Resolution: Invalid
    Fix Version/s:     (was: 5.0.10)
         Assignee: Howard M. Lewis Ship

The TextField component is doing exactly what it should be doing here ... it is reading and updating the currentObject property.  The fact that your code doesn't do anything with the update value is an aspect of your application.

In the real world, you would be pulling complex entity objects from a database and editting properties of those entities.  As long as you persist changes to your external store (database), then you'll get the behavior you expect.
