              Hi,


              You should write an bean which takes the values and store them in the database. You only have two entity beans which by themselves don't do much.


              So something like the following.



              @Name("wadhahBean")
              @Scope(CONVERSATION)
              public class WadHahBean implements  Serializable {
              
                @In protected EntityManager entityManager;
              
              
                private User user;  
                private List<Role> selectedRoles;  
              
                @Begin(join=true)
                public void init(){
                 ///.... Do something which inits your page vars and selects your user and get the roles
                  selectedRoles = new ArrayList<Role>(user.getRoles());
                }
              
                @Transactional
                public void save(){
                 user.setRoles(new HashSet(selectedRoles));
                 entityManager.persist(user.setRoles());
                }
              
              }






              Now you can save the UserRoles by doing:





              <h:selectManyCheckbox value="#{wadhahBean.selectedRoles}">
                   <f:selectItem itemLabel="Agent" itemValue="Agent" />
                   <f:selectItem itemLabel="Admin" itemValue="Admin" />
              </h:selectManyCheckbox>



              It's just a first draft, soyou should work on it.

                    Hi,


                    you need setter and getters for each property. I didn't add those for brevity, but you need them to work.

                        Hi,


                        you should use:




                        #{Register.selectedRoles}



                        You use directly the propertyname of the bean without set/get

                          Hi,


                          I also think there is something wrong with your configuration, because ith should return an error property not found on the beanname and not on Object.


                          Check the previous first and see if it works. If not give some configuration data (components.xml)

                              Hi,


                              Are the Seam interceptor in place ? In other words: because you don't have such an annotation on the satles bean, there should be one defined in the file ejb-jar-xml That file should look like the following. I see that you're basically using a Seam-gen project so I assume that the rest of the settings in the different files is correct.


                              To make a quick check to see if the bean is available you could:


                              - See if the bean is registered in JNDI. If you use Jboss you can use the management tools of the server.
                              - To see if the bean exists and is intercepted correctly, create whatever init method, put a @Create annotation on that method and do some logging in the method.


                              The thing what really worries me is the fact that the error is on the JavaAssist on not on some component name.
