I'm now looking at the Interface21's FormControllerTestSuite
http://fisheye1.cenqua.com/browse/springframework/i21/test/com/interface21/web/servlet/mvc/FormControllerTestSuite.java?r=MAIN
They have implemented a formBackingObject() method in their TestController
class (way on the bottom...)
TestController extends SimpleFormController
Admittedly, they don't have a service layer for the tests that use
TestController, but why is it that someone would use formBackingObject or
bindOnNewForm? (since I don't seem to be able to find any semi-complex
examples of this... )
