inputText not rendered inside selectOneMenu

[jacinh]

Hi,

I have searched other discussions on the forum but can't seem to find a workng solution.

I am trying to render additional input text fields based on the selection from a selectOneMenu.  However, the value I enter into the inputText field is not being submitted (setter not called).   For example, when i select option b, and enter value into value2 input field, it doesn't seem to think the field is rendered, eventhough it's rendered on screen.

My code:

<h:panelGrid>
      <a4j:form id="block">
        <a4j:region>
          <h:selectOneMenu value="#{testBean.option}" immediate="true">
            <f:selectItem itemValue="a" />
            <f:selectItem itemValue="b" />
            <f:selectItem itemValue="c" />
            <a4j:support event="onchange" reRender="block"
              ajaxSingle="true" />
          </h:selectOneMenu>
        </a4j:region>
        <h:outputText value="block A " rendered="#{testBean.option=='a'}" />
        <h:inputText value="#{testBean.value1}" id="value1"
          rendered="#{testBean.option=='a'}"></h:inputText>
        <h:outputText value="block B " rendered="#{testBean.option=='b'}" />
        <h:inputText value="#{testBean.value2}" id="value2"
          rendered="#{testBean.option=='b'}"></h:inputText>
        <h:outputText value="block C " rendered="#{testBean.option=='c'}" />
        <h:inputText value="#{testBean.value3}" id="value3"
          rendered="#{testBean.option=='c'}"></h:inputText>
        <a4j:commandButton styleClass="" value="Submit"
          action="#{testBean.save}" />
      </a4j:form>
    </h:panelGrid>

Any input apprediated!!

testBean should be session scoped in order this to work.

And b.t.w. if you using ajaxSingle at support you could remove region and immediate=true .

thanks for your reply, Ilya!

I tried your advice and it does work, but I can't see why it'd work for session not request.  My bean really has to be request scoped.  Is there a way to make this work in request scope?

I found another similar discussion that's why I wrapped my selectOneMenu with <a4j:region> tags, but it doesn't work.

Am I on the wrong track?  I just want to show some additional input fields based on user's selectOneMenu selection.  This should be a very common use-case?  Can it be accomplished some other way?

your bean have to be stored between requests. There are different ways - session scope, long running conversation if seam used, or a4j:keeAlive. Read about the problem there http://livedemo.exadel.com/richfaces-demo/richfaces/keepAlive.jsf;jsessionid=6B48599000B855C89CEA7EF0D08E41E3?c=keepAlive&tab=usage and the same write-up in wiki faq.
