    Second click problem resolved

      Ilya are right. There is no intervention required.

       

      Two different ajax views should be handled in ONE form, and

      not in two separate.

       

      A simple example shows it:

       

       

      <ui:define name="top">

                   <h:form>

                   <h:panelGrid id="panel" columns="5">

       

                     <h:panelGroup rendered="#{!loginBean.loggedIn}">

       

                     <!--  <ui:include src="/sections/header/loginHeader.xhtml"/> -->

                     <div style="width:60%;font-size:14px;line-height:42px;background-color:white;color:black">

       

       

                         <h:outputText value="#{msg.name}" />

                         <h:inputText value="#{loginBean.alias}" required="true" />

                         <h:outputText value="#{msg.pwd}" />

                         <h:inputSecret  value="#{loginBean.password}"  required="true" />

                         <h:commandButton value="Login" action="#{loginBean.checkLogin}" >

                            <a4j:ajax execute="@form" render=":refl" />

                         </h:commandButton>                

       

                     </div>

                     </h:panelGroup>

       

                     <h:panelGroup rendered="#{loginBean.loggedIn}">

                        <!-- <ui:include src="/sections/header/logoutHeader.xhtml"/> -->

       

                         <h:commandButton value="Logout" action="#{loginBean.logout}" >

                            <a4j:ajax execute="@form" render=":refl" />

                          </h:commandButton>

       

       

                     </h:panelGroup>

       

                   </h:panelGrid>

                   </h:form> 

              </ui:define>

       

       

      The two commandButton tags should not be respectivaly suround with (<form></form>) tags.

            Why is that so?

             

            Why do I have to put two different ajax calls of a page within the SAME form ?

             

             

            I have had the same problem. When using two different forms and submitting a selectOneMenu of the second form via ajax by selecting an item nothing happens. When selecting again, the item is being selected successfully. So I have to select twice because the first select is ignored. Why is that so?

             

            When putting the selectOneMenu of the second form into the first form and do the ajax-select, then it works

                It should be best practice to minimize the content within a form - why I am forced to wrap ALL my input-fields and the like within ONE form only to make ajax-calls? Of course, I can minimze the execute-tags but normally I want to logically group views into different forms and not into one whole form.

                  It's logically not always a good solution.

                   

                  If you have all in separate files, think about this.

                   

                  If you have a conditionally rendering, so that only

                  one component is rendered, the you can have to much

                  tags in your end script.

                   

                  Suddenly in your client html script,

                  you can have such :

                   

                  <form>

                  --- the rendered part ---

                  </form>

                  <form>

                  --- the not rendered part ---

                  </form>

                   

                  But we need is only such:

                   

                  <form>

                  --- the rendered part ---

                  </form>
