Problems with converter in h:selectManyCheckbox

[Juan Manuel Diaz]

Hi fellows!, I am trying to implement a CRUD for users in my web app. I am using JSF2.0, spring 3 and hibernate. The problem is when i use h:selectManyCheckbox for user roles. I am always getting a convertion error message when i press save button. I am using a FacesConverter for convertion.

This is my code:

The backing bean:

import com.zien.barmanagement.model.AuthorityRole;
import com.zien.barmanagement.model.CustomUser;
import com.zien.barmanagement.services.impl.UserDetailsServiceImpl;
import java.util.Arrays;
import java.util.List;
import java.util.Set;
import javax.annotation.Resource;
import org.richfaces.component.UIDataTable;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

/**
 *
 * @author Juan M. Diaz
 */
@Controller
@Scope("session")
public class UserBean extends AbstractBean{

    @Resource
    private UserDetailsServiceImpl userDetailsService;

    private CustomUser user;

    private UIDataTable userDataTable;


    /**
     * @return the userDetailsService
     */
    public UserDetailsServiceImpl getUserDetailsService() {
        return userDetailsService;
    }

    /**
     * @param userDetailsService the userDetailsService to set
     */
    public void setUserDetailsService(UserDetailsServiceImpl userDetailsService) {
        this.userDetailsService = userDetailsService;
    }

    /**
     * @return the user
     */
    public CustomUser getUser() {
        return user;
    }

    /**
     * @param user the user to set
     */
    public void setUser(CustomUser user) {
        this.user = user;
    }

    /**
     * @return the userDataTable
     */
    public UIDataTable getUserDataTable() {
        return userDataTable;
    }

    /**
     * @param userDataTable the userDataTable to set
     */
    public void setUserDataTable(UIDataTable userDataTable) {
        this.userDataTable = userDataTable;
    }


    public String edit(){
        CustomUser selectedUser;
        try{
            selectedUser = (CustomUser)getUserDataTable().getRowData();
        } catch (Exception e) {
            selectedUser = userDetailsService.newUser();
        }

        this.setUser(selectedUser);

        return this.getUrlFor(BeanConst.USER_EDIT_SHOW);
    }

    public List<AuthorityRole> getAvailableRoles(){
        return userDetailsService.getAvailableRoles();
    }
    
    public String save(){
        userDetailsService.persist(this.getUser());
        return this.getUrlFor(BeanConst.ADMIN_HOME);
    }

    public String home(){
        return this.getUrlFor(BeanConst.TICKETS_HOME);
    }

    /**
     * @return the selectedRoles
     */
    public AuthorityRole[] getSelectedRoles() {
        return (AuthorityRole[]) this.user.getRoles().toArray(new AuthorityRole[0]);
    }

    /**
     * @param selectedRoles the selectedRoles to set
     */
    public void setSelectedRoles(AuthorityRole[] selectedRoles) {
        this.user.setRoles((Set<AuthorityRole>) Arrays.asList(selectedRoles));
    }
}

My FacesConverter for AuthorityRole class

import com.zien.barmanagement.model.AuthorityRole;
import com.zien.barmanagement.services.impl.UserDetailsServiceImpl;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.FacesConverter;
import org.springframework.web.jsf.FacesContextUtils;

/**
 *
 * @author Juan M. Diaz
 */
@FacesConverter(value="authorityRoleConverter", forClass=AuthorityRole.class)
public class AuthorityRoleConverter implements Converter {

    private UserDetailsServiceImpl userDetailsService;

    public Object getAsObject(FacesContext fc, UIComponent uic, String string) {
        if (this.userDetailsService == null){
            this.userDetailsService = (UserDetailsServiceImpl) FacesContextUtils.getWebApplicationContext(fc).getBean("userDetailsService");
        }
        return this.getUserDetailsService().getAuthorityRoleById(Integer.getInteger(string));
    }

    public String getAsString(FacesContext fc, UIComponent uic, Object o) {
        return ((AuthorityRole) o).getId().toString();
    }

    /**
     * @return the userDetailsService
     */
    public UserDetailsServiceImpl getUserDetailsService() {
        return userDetailsService;
    }

    /**
     * @param userDetailsService the userDetailsService to set
     */
    public void setUserDetailsService(UserDetailsServiceImpl userDetailsService) {
        this.userDetailsService = userDetailsService;
    }
}

And finally, my facelet:

    <ui:define name="content">
        <h:form>
            <rich:panel header="Editar usuario #{userBean.user.username}">
                <h:panelGrid columns="2" >
                    <h:outputLabel for="username" value="Nombre de usuario: " />
                    <h:inputText id="username" value="#{userBean.user.username}" />
                    <h:outputLabel for="password" value="Contraseña: " />
                    <h:inputSecret id="password"  value="#{userBean.user.password}" />
                    <h:outputLabel for="name" value="Nombre: " />
                    <h:inputText id="name" value="#{userBean.user.firstName}" />
                    <h:outputLabel for="lastname" value="Apellido: " />
                    <h:inputText id="lastname" value="#{userBean.user.lastName}" />
                    <h:outputLabel for="email" value="Email: " />
                    <h:inputText id="email" value="#{userBean.user.email}" />
                    <h:outputLabel for="enabled" value="Habilitado: " />
                    <h:selectBooleanCheckbox id="enabled" value="#{userBean.user.enabled}" />
                    <h:outputLabel value="Roles:"/>
                    <h:column />
                    <h:selectManyCheckbox value="#{userBean.selectedRoles}" />
                        <f:selectItems value="#{userBean.availableRoles}" var="role" itemLabel="#{role.summary}" />
                        <f:converter converterId="authorityRoleConverter" />
                    </h:selectManyCheckbox>
                    <h:commandButton value="Guardar" action="#{userBean.save}" />
                </h:panelGrid>
            </rich:panel>
        </h:form>
    </ui:define>

I really dont know what I am doing wrong, but I tried a lot of modifications to the above code and i always get the convertion error message.

Ideas are welcome!
