    Enrity dirty checking in flushMode=MANUAL

    Martin Goik Newbie

      I do have an Entity User and a corresponding UserHome with manual flushing enabled:

      public class UserHome extends EntityHome<User> {
        @In(create=true ) private EntityInfoManager entityInfoManager;
        private String pw1, pw2;
        public String update() {
          final User u = getInstance();
          if (someCondition) {
            return null;
          } else {
          return super.update();
        @Begin(flushMode=FlushModeType.MANUAL, join=true)
        public void create() {
          //business logic code omitted

      The corresponding view user.xhtml contains:

      <h:commandButton id="update" value="Update" action="#{userHome.update}"
      rendered="#{userHome.managed}" />

      The User entity references other entities that may or may not be changed in the conversation and so far it works.

      Now I want to display this update button shaded as long as no entity has been changed. In other words: I want to know if the User instance object or any referenced object within the conversation is in a dirty state.

      I searched the Seam documentation and this (plus the former) Seam user's forum but did not find any hint.
