I have this menu: <h:selectOneMenu value=#{ApplicationController.settings[‘SessionTTL’]}> <f:selectItem itemValue=60 itemLabel=1 hour /> <f:selectItem itemValue=30 itemLabel=30

  • 0

I have this menu:

<h:selectOneMenu value="#{ApplicationController.settings['SessionTTL']}">
    <f:selectItem itemValue="60" itemLabel="1 hour" />
    <f:selectItem itemValue="30" itemLabel="30 Minutes" />
    <f:selectItem itemValue="20" itemLabel="20 Minutes" />
    <f:selectItem itemValue="10" itemLabel="10 Minutes" />
    <f:selectItem itemValue="custom" itemLabel="Define custom value" />
    <f:ajax render="input" />
</h:selectOneMenu>&nbsp;
<h:panelGroup id="input">
    <h:inputText value="#{ApplicationController.settings['SessionTTL']}" rendered="#{ApplicationController.settings['SessionTTL'] == 'custom'}" required="true" />
</h:panelGroup>

The problem is that I cannot see the value into the menu label. When I click custom and I update it, I always get 1 hour. If I modify this way the menu:

<h:selectOneMenu value="#{ApplicationController.settings['SessionTTL']}">
    <f:selectItem itemValue="#{ApplicationController.settings['SessionTTL']}" itemLabel="#{ApplicationController.settings['SessionTTL']}" />
    <f:selectItem itemValue="60" itemLabel="1 hour" />
    <f:selectItem itemValue="30" itemLabel="30 Minutes" />
    <f:selectItem itemValue="20" itemLabel="20 Minutes" />
    <f:selectItem itemValue="10" itemLabel="10 Minutes" />
    <f:selectItem itemValue="custom" itemLabel="Define custom value" />
    <f:ajax render="input" />
</h:selectOneMenu>&nbsp;
<h:panelGroup id="input">
    <h:inputText value="#{ApplicationController.settings['SessionTTL']}" rendered="#{ApplicationController.settings['SessionTTL'] == 'custom'}" required="true" />
</h:panelGroup>

I always get the first value into the menu label . Do you know why I cannot display the custom value into the menu label?

    Based in your update, you just need to update the inputText using JavaScript, no need to add the rendered attribute, nor an panelGroup wrapping the value.

    <script type="text/javascript">
    function updateInputText(ddlChanged, inputTextId) {
        var realId= "settingsupdate:" + inputTextId;
        document.getElementById("realId").value = 
            ddlChanged.options[ddlChanged.selectedIndex].text;
    }
</script>
<h:form id="settingsupdate">
    <!-- another components... -->
    <h:selectOneMenu id="ddlMyOptions" value="#{GeneralController.settings['InitState']}"
        onchange="updateInputText(this, 'txtMyText');">
        <f:selectItem itemValue="1" itemLabel="Level 1" />
        <f:selectItem itemValue="2" itemLabel="Level 2" />
        <f:selectItem itemValue="3" itemLabel="Level 3" />
        <f:selectItem itemValue="custom" itemLabel="Define custom value" />
    </h:selectOneMenu>
    <h:inputText id="txtMyText" />
</h:form>
