As a result of http://forum.springframework.org/showthread.php?t=39757 we started to doubt about the clearity of the setupForm methods javadoc.

There is a reference to the createFormObject method however this can lead to confusions. It is assumed by some that the createFormObject method is called each time setupForm is called. However the createFormObject is only called when no form object is currently present in the configured scope. This can be made clearer in the javadocs.
