Hello,

I'm trying to create a multiaction web controller using Spring annotations. This controller will be responsible for adding and removing user profiles and preparing reference data for the jsp page.

@Controller
public class ManageProfilesController {
    @InitBinder
    public void initBinder(WebDataBinder binder) { 
        binder.registerCustomEditor(UserAccount.class,"account", new UserAccountPropertyEditor(userManager)); 
        binder.registerCustomEditor(Profile.class, "profile", new ProfilePropertyEditor(profileManager));
        logger.info("Editors registered");
    }

    @RequestMapping("remove")
    public void up( @RequestParam("account") UserAccount account,
                @RequestParam("profile") Profile profile) {
        ...
    }

    @RequestMapping("")
    public ModelAndView defaultView(@RequestParam("account") UserAccount account) {
        logger.info("Default view handling");
        ModelAndView mav = new ModelAndView();
        logger.info(account.getLogin());
        mav.addObject("account", account);
        mav.addObject("profiles", profileManager.getProfiles());
        mav.setViewName(view);
        return mav;
    }
    ...
}

Here is the part of my webContext.xml file:

<context:component-scan base-package="ru.mirea.rea.webapp.controllers" />
<context:annotation-config/>
<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
            <value>
               ...
              /home/users/manageProfiles=users.manageProfilesController
            </value>
    </property>
</bean>

<bean id="users.manageProfilesController" class="ru.mirea.rea.webapp.controllers.users.ManageProfilesController">
    <property name="view" value="home\users\manageProfiles"/>
</bean>
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

However, when i open the mapped url, i get exception:

java.lang.IllegalArgumentException: Cannot convert value of type [java.lang.String] to required type [ru.mirea.rea.model.UserAccount]: no matching editors or conversion strategy found

I use spring 2.5.6 and plan to move to the Spring 3.0 in some not very distant future. However, according to this JIRA https://jira.springsource.org/browse/SPR-4182 it should be possible already in spring 2.5.1.

The debug shows that the InitBinder method is correctly called.

What am i doing wrong?
