how to fixe twice needed click inside JSF page? [duplicate]

Answer 1

It is a bug of JSF,JAVASERVERFACES_SPEC_PUBLIC-790 , and will be fixed in version 2.3. (thanks to BalusC for correcting my post.)

You can use this script to solve the issue.

Here is a good answer about the invokation of commandLink and commandButton. I also suggest you to design your page accordingly.

However, there is a PrimeFaces solution which works for me. It works if you give the button which form will be proceed and which will be rendered after ajax request.

    <h:form id="page1">

    <p:commandButton value="" action="#{some_action}">
   <f:ajax execute="@form" render=":page2" />
    </p:commandButton>    
    </h:form>

your action returns to page2

<h:form id="page2">

Some Components

</h:form>
