I still have not found a solution.  If you guys need more info/code just let me know.  I think it might be how equals is being called.  I put in some log statements and its comparing things that are not equal.

Heres the java code for the class:

@Entity
@Name( "role" )
public class Role implements Serializable {

     private String roleId;
     private String description;

     private List<User> users;

     public Role() {
          
          super();
     }
     
     public Role( String roleId ) {

          super();
          this.roleId = roleId;
     }
     
     public Role( String roleId, String description ) {

          super();
          this.roleId = roleId;
          this.description = description;
     }

     @Id
     public String getRoleId() {

          return roleId;
     }

     public void setRoleId( String roleId ) {

          this.roleId = roleId;
     }

     public String getDescription() {

          return description;
     }

     public void setDescription( String description ) {

          this.description = description;
     }

     @ManyToMany( cascade = { CascadeType.REMOVE }, fetch = FetchType.EAGER, mappedBy = "roles" )
     @JoinTable( name = "UserRole", joinColumns = { @JoinColumn( name = "userId" ) }, inverseJoinColumns = { @JoinColumn( name = "roleId" ) } )
     public List<User> getUsers() {

          return this.users;
     }

     public void setUsers( List<User> users ) {

          this.users = users;
     }

     @Override
     public int hashCode() {

          final int prime = 31;
          int result = 1;
          result = prime * result + ((description == null) ? 0 : description.hashCode());
          result = prime * result + ((roleId == null) ? 0 : roleId.hashCode());
          return result;
     }

     @Override
     public boolean equals( Object obj ) {

          System.out.print( "---------- Comparing " + this.toString() + " to " + obj.toString() + ". ----------");
          if (this == obj) {
               System.out.println( "[TRUE] Addresses are the same." );
               return true;
          }
          if (obj == null) {
               System.out.println( "[FALSE] Obj is null." );
               return false;
          }
          if (getClass() != obj.getClass()) {
               System.out.println( "[FALSE] Classes arent the same." );
               return false;
          }
          final Role other = (Role) obj;
          
          if (description == null) {
               if (other.description != null) {
                    System.out.println( "[FALSE] Description on other is null." );
                    return false;
               }
          }
          else if (!description.equals( other.description )) {
               System.out.println( "[FALSE] Descriptions not equal." );
               System.out.println( "This: " + this.getDescription() );
               System.out.println( "Other: " + other.getDescription() );
               return false;
          }
          if (roleId == null) {
               if (other.roleId != null) {
                    System.out.println( "[FALSE] RoleId on other is null." );
                    return false;
               }
          }
          else if (!roleId.equals( other.roleId )) {
               System.out.println( "[FALSE] RoleIds not equal." );
               return false;
          }

          System.out.println( "[TRUE] Passed all tests." );
          return true;
     }

     @Override
     public String toString() {
          
          return roleId;
     }
}

And this is the output:

08:41:42,295 INFO  [STDOUT] ---------- Comparing employee to admin. ----------

As you can see, its doing some strange things.  I think I have .equals implemented correctly, but Im not so sure about the action(s) and the actual shuttle.  The error message that I am getting seems to be related to this because it doesnt pass the equals and it fails first with the role admin and that is the role referenced in the error.  Any ideas?

Thanks

Thank you for the reply.  I tried adding the suggested tag and removing the converter attribute from the shuttle.  When trying to navigate to the page i get the following exception:

com.sun.facelets.tag.TagException: /userModalPanels.xhtml @102,27 <s:entityConverter> Tag Library supports namespace: http://jboss.com/products/seam/taglib, but no tag was defined for name: entityConverter

Im pretty sure I have the required tag library included.  These are the ones I have:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
                xmlns:s="http://jboss.com/products/seam/taglib"
                xmlns:ui="http://java.sun.com/jsf/facelets"
                xmlns:f="http://java.sun.com/jsf/core"
                xmlns:h="http://java.sun.com/jsf/html"
                xmlns:rich="http://richfaces.org/rich"
                xmlns:a4j="http://richfaces.org/a4j">

Ive got it now where it will recognize the tag, however, Im still getting the same validation error on admin when I try to save the changes.

I dont have any required attributes in this form, but I do in a separate form not related to this one.  I do have a few access rules in security.drl implemented to limit access to the console page and the employee page.  I havent had any problems accessing these with any of my other POSTs (creates, edits, deletes, reads, role editing separate from these for now).

Here is the code to give you a better idea of what Ive implemented as far as validation goes:

security.drl:

package Permissions;

import java.security.Principal;

import org.jboss.seam.security.PermissionCheck;
import org.jboss.seam.security.Role;

rule CanUserViewEmployeeHome
when
        c: PermissionCheck( name == "/employeeHome.xhtml", action == "render" )
        Role( name == "employee" )
then
        c.grant();
end

rule CanUserViewConsole
when
        c: PermissionCheck( name == "/console.xhtml" )
        Role( name == "admin" )
then
        c.grant();
end

pages.xml:

    <page view-id="/employeeHome.xhtml" login-required="true">
        <restrict />
    </page>
    
    <page view-id="/console.xhtml" login-required="true">
        <restrict />
    </page>

And the code for the shuttle (note: no required attributes were used):

       <rich:modalPanel id="editUserRolePanel" width="300" height="100">
                <f:facet name="header">
                        <h:outputText value="Add/Remove Roles" />
                </f:facet>

        <s:div id="userRolesToEdit">
                        <h:form>
                                <rich:listShuttle id="roleShuttle" sourceValue="#{usermanager.unassignedRoles}" targetValue="#{user.roles}" var="r" fastOrderControlsVisible="false" orderControlsVisible="false">
                                        <s:convertEntity></s:convertEntity>
                                        <rich:column>
                                                <h:outputText value="#{r.roleId}" />
                                        </rich:column>
                                </rich:listShuttle>
                                
                                <rich:spacer height="15" />
                                
                                <center>
                                        <h:commandButton value="Save" action="#{usermanager.edit}" oncomplete="Richfaces.hideModalPanel('editUserRolePanel'); return false" reRender="usersTable" />
                                <h:commandButton value="Cancel" action="#{usermanager.cancel}" oncomplete="Richfaces.hideModalPanel('editUserRolePanel'); return false" />
                        </center>
                        </h:form>
                </s:div>
        </rich:modalPanel>

So as far as I know, I am not doing any other validation, unless there is something other from the above that I have missed.  Is there any default settings I should know about from the generic Seam login application?

Ive removed the oncompletes and the associated javascript stuff.  They were only there because I thought they were necessary to close the modal panels (got that from a richfaces tutorial).  The whole page should refresh at this point because I am using the normal html command buttons.  I still get the same error as before:

16:34:52,350 INFO  [lifecycle] WARNING: FacesMessage(s) have been enqueued, but may not have been displayed.
sourceId=j_id54:roleShuttle[severity=(ERROR 2), summary=(j_id54:roleShuttle: Validation Error: Value admin is not valid), detail=(j_id54:roleShuttle: Validation Error: Value admin is not valid)]

The edit action is not getting called... forgot to mention that.

Yes that makes sense and was originally what I was doing until my boss for some reason or other told me to check everything but the List objects (which went against what I learned in school).  He knew I was having problems with this, so I guess his rational was 'check all the bases to be safe.'  roleId is the primary key, and is the only thing that is unique in the table.  It didnt make sense to be doing all those extra checks against attributes that were not unique, but oh well.  Ill take them out and give it a try and I'll let you know how it goes.

Same error still.

I think I might've found a useful/related topic in the JBoss Seam Forum concerning my problem:

http://www.jboss.com/index.html?module=bb&op=viewtopic&t=128067

I think this MIGHT be my problem, as I myself did not put any validation in.  The only thing is though I am not specifically using the edit.xhtml anywhere in my code, so Im not sure how it would be reaching the validateAll tag.

Any thoughts?
