I am writing my first Spring 3.0.5 MVC app and am confused about why my controller mappings aren't doing what I expect.

I have a VerifyPasswordController that is called after a user tries to log in by entering his name and password.

// Called upon clicking "submit" from /login
@RequestMapping(value = "/verifyPassword", method = RequestMethod.POST)
@ModelAttribute("user")
public String verifyPassword(User user,
        BindingResult result) {

    String email = user.getEmail();
    String nextPage = CHOOSE_OPERATION_PAGE; // success case
    if (result.hasErrors()) {
        nextPage = LOGIN_PAGE;
    } else if (!passwordMatches(email, user.getPassword())) {
        nextPage = LOGIN_FAILURE_PAGE;
    } else {
        // success
    }
    return nextPage;
 }

I can verify in the debugger that this method is being called, but afterwards, the verifyPassword page is displayed rather than the chooseOperation page. The console output of WebLogic seems to show that my mapping are correct:

INFO : org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping - Mapped URL path [/chooseOperation] onto handler 'chooseOperationController'
INFO : org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping - Mapped URL path [/chooseOperation.*] onto handler 'chooseOperationController'
INFO : org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping - Mapped URL path [/chooseOperation/] onto handler 'chooseOperationController'

Here is the ChooseOperationController:

@Controller
@SessionAttributes("leaveRequestForm")
public class ChooseOperationController implements PageIfc, AttributeIfc {

    @RequestMapping(value = "/chooseOperation")
    @ModelAttribute("leaveRequestForm")
    public LeaveRequest setUpLeaveRequestForm(
            @RequestParam(NAME_ATTRIBUTE) String name) {
        LeaveRequest form = populateFormFromDatabase(name);
        return form;
    }

    // helper methods omited
}

I welcome any advice, particularly "generic" techniques for debugging such mapping problems. BTW, I've also tried to "redirect" to the desired page, but got the same result.
