Hi,

Also face this problem. But when put String into SelectItem seems to be working. Only when put in object the validation error occurs.

My bean code is as below:
    public UIComponentBase getUserGroupsList(){
        EntityManager em = getEntityManager();
         listUserGroup = (List <UserGroup>) em.createQuery("select o from UserGroup as o").getResultList();
         
         
         list=new UISelectMany();
         System.out.println("sizeof list:"+listUserGroup.size());
         
         SelectItem item = new SelectItem();
            for(UserGroup x : listUserGroup) {
                    item = new SelectItem(x);
                                 
         UISelectItem uiItem = new UISelectItem();
         uiItem.setValue( item );
         
         list.getChildren().add( uiItem );
         }
      return list;
    }

The web page code :

                    <h:outputText value="User Group Assigned:"/>
                    <h:selectManyListbox binding="#{user.userGroupsList}">
