    How to include an object that has a list element?

    Luiz Soares Newbie

      I have an object called Perfil that has an OneToMany relationship with another object called Nivel.
      So, in the Perfil Entity I have a Nivel list.


      When I have to include a Perfil, I have to include a new Nivel because some attributes that I've to include, view or edit are in the Nivel table.


      So, my question is: How to include a new Perfil using the Nivel list?


      I tried something like this, but didn't work out.


      <s:decorate id="nmPerfilField" template="layout/edit.xhtml">
                      <ui:define name="label">Nome Perfil</ui:define>
                      <h:inputText id="nmPerfil"
                             required="true"
                                 size="50"
                            maxlength="50"
                                value="#{pmnPerfilHome.instance.nmPerfil}">
                          <a:support event="onblur" reRender="nmPerfilField" bypassUpdates="true" ajaxSingle="true"/>
                      </h:inputText>
                  </s:decorate>
                  
                  <s:decorate id="nmNivelField" template="layout/edit.xhtml" rendered="#{pmnPerfilHome.managed}">
                      <ui:define name="label">Nome Nível</ui:define>
                      <h:inputText id="nmNivel"
                             required="true"
                                 size="50"
                            maxlength="50"
                                value="#{pmnPerfilHome.instance.pmnNivels.add(0,nmNivel)}">
                          <a:support event="onblur" reRender="nmNivelField" bypassUpdates="true" ajaxSingle="true"/>
                      </h:inputText>
                  </s:decorate>



      Here goes my Perfil Entity:


      ......
        private List<PmnNivel> pmnNivels = new ArrayList<PmnNivel>(0);
        ......
        @OneToMany(fetch = FetchType.LAZY, mappedBy = "pmnPerfil")
           public List<PmnNivel> getPmnNivels() {
                return this.pmnNivels;
           }
      
           public void setPmnNivels(List<PmnNivel> pmnNivels) {
                this.pmnNivels = pmnNivels;
           }
      



      There's a method in the Perfil Home Object:


      public List<PmnNivel> getPmnNivels() {
                return getInstance() == null ? null : new ArrayList<PmnNivel>(
                          getInstance().getPmnNivels());
           }
      



      Thanks for your help!
