Failed to convert value of type to required type Java Spring MVC

Собственно вопрос очень старый но решения так и нет. Обсуждался тут https://stackoverflow.com/questions/43041724/using-converter-with-spring-mvc и тут https://stackoverflow.com/questions/50173341/field-error-in-object-user-on-field-userprofiles-rejected-value-3 Моя проблема в точности та же самая За основу взят этот пример http://websystique.com/springmvc/spring-mvc-4-and-spring-security-4-integration-example/ Только пример я расширил с возможностью добавления в базу ролей и привилегий Для этого модифицировал модель ролей так

@Table(name="USER_PROFILE")
public class UserProfile implements Serializable{

	@Id @GeneratedValue(strategy=GenerationType.IDENTITY)
	private Integer id;

	@NotEmpty
	@Column(name="TYPE", unique=true, nullable=false)
	private String type;

	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}

	public String getType() {
		return type;
	}
	public void setType(String type) {
		this.type = type;
	}


	@NotEmpty
//	@ManyToMany(fetch = FetchType.EAGER, cascade = {CascadeType.PERSIST, CascadeType.MERGE})
	@ManyToMany(fetch = FetchType.EAGER)
	@Fetch(value = FetchMode.SUBSELECT)
	@JoinTable(name = "USER_PROFILE_USER_PERMISSION",
			joinColumns = { @JoinColumn(name = "USER_PROFILE_ID") },
			inverseJoinColumns = { @JoinColumn(name = "USER_PERMISSION_ID") })

	private Set<UserPermission> userPermissions = new HashSet<UserPermission>();

	public Set<UserPermission> getUserPermissions() {
		return userPermissions;
	}

	public void setUserPermissions(Set<UserPermission> userPermissions) {
		this.userPermissions = userPermissions;
	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + ((id == null) ? 0 : id.hashCode());
		result = prime * result + ((type == null) ? 0 : type.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (!(obj instanceof UserProfile))
			return false;
		UserProfile other = (UserProfile) obj;
		if (id == null) {
			if (other.id != null)
				return false;
		} else if (!id.equals(other.id))
			return false;
		if (type == null) {
			if (other.type != null)
				return false;
		} else if (!type.equals(other.type))
			return false;
		return true;
	}

	@Override
	public String toString() {
		return "UserProfile [id=" + id + ", type=" + type + ",  userPermissions=" + userPermissions + "]";
	}
}

Метод добавления роли в контроллере

@RequestMapping(value = { "/newprofile" }, method = RequestMethod.POST)
public String saveUserProfile(@Valid UserProfile userProfile, BindingResult result,
							  ModelMap model) {

	if (result.hasErrors()) {
		return "profiles";
	}

	if(!userProfileService.isUserProfileTypeUnique(userProfile.getId(), userProfile.getType())){
		FieldError ssoError = new FieldError("userProfile","type",messageSource.getMessage("non.unique.type", new String[]{userProfile.getType()}, Locale.getDefault()));
		result.addError(ssoError);
		return "newprofile";
	}

	userProfileService.saveProfile(userProfile);

	model.addAttribute("success", "UserProfile " + userProfile.getType() + " registered successfully");
	model.addAttribute("loggedinuser", getPrincipal());
	return "layouts/registrationsuccess";
}

Конвертор привилегий выглядит так

@Component
public class PrivilegeToUserPermissionConverter implements Converter<Object, UserPermission>{

	static final Logger logger = LoggerFactory.getLogger(PrivilegeToUserPermissionConverter.class);

	@Autowired
	UserPermissionService userPermissionService;

	/**
	 * Gets UserProfile by Id
	 * @see org.springframework.core.convert.converter.Converter#convert(java.lang.Object)
	 */
	public UserPermission convert(Object element) {
		Integer id = Integer.parseInt((String)element);
		UserPermission permission= userPermissionService.findById(id);
		logger.info("Permission : {}",permission);
		return permission;
	}
}

Добавить новую роль (UserProfile) невозможно. Возникает ошибка типа

Failed to bind request element: org.springframework.beans.TypeMismatchException: Failed to convert value of type [com.websystique.springmvc.model.UserProfile] to required type [com.websystique.springmvc.model.UserProfile]; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [com.websystique.springmvc.model.UserProfile] to type [@javax.validation.Valid com.websystique.springmvc.model.UserProfile] for value 'UserProfile [id=null, type=dgfhsdhsf,  userPermissions=[com.websystique.springmvc.model.UserPermission@62ce11d]]'; nested exception is java.lang.ClassCastException: com.websystique.springmvc.model.UserProfile cannot be cast to java.lang.String

Собственно проект тут https://bitbucket.org/yguvin/springmvchibernatewithspringsecurity/src/master/ Проблема в том что регистрация двух конверторов в public class AppConfig extends WebMvcConfigurerAdapter{ приводит к вышеописанной ошибке

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.websystique.springmvc")
public class AppConfig extends WebMvcConfigurerAdapter{


	@Autowired
	RoleToUserProfileConverter roleToUserProfileConverter;

	@Autowired
	PrivilegeToUserPermissionConverter privilegeToUserPermissionConverter;


	/**
     * Configure ViewResolvers to deliver preferred views.
     */
	@Override
	public void configureViewResolvers(ViewResolverRegistry registry) {

		InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
		viewResolver.setViewClass(JstlView.class);
		viewResolver.setPrefix("/WEB-INF/views/");
		viewResolver.setSuffix(".jsp");
		registry.viewResolver(viewResolver);
	}

	/**
     * Configure ResourceHandlers to serve static resources like CSS/ Javascript etc...
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
		registry.addResourceHandler("/static/**").addResourceLocations("/static/");
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
		registry.addResourceHandler("/resources/css/**").addResourceLocations("/resources/css/").setCachePeriod(31556926);
		registry.addResourceHandler("/resources/img/**").addResourceLocations("/resources/img/").setCachePeriod(31556926);
		registry.addResourceHandler("/resources/js/**").addResourceLocations("/resources/js/").setCachePeriod(31556926);
    }

    /**
     * Configure Converter to be used.
     * In our example, we need a converter to convert string values[Roles] to UserProfiles in newUser.jsp
     */
    @Override
    public void addFormatters(FormatterRegistry registry) {

    	registry.addConverter(roleToUserProfileConverter);
	registry.addConverter(privilegeToUserPermissionConverter);
    }

    /**

    @Bean

	    messageSource.setBasename("messages");
	    return messageSource;

Косяк Спринга? Не может быть. Тогда что? Решения задачки в сети нет. Может ли кто подсказать как выполнить конвертацию данных непосредственно в контроллере, без применения компонентов конверторов?
