Question

I’m trying to submit a form when a selectOneRadio value is selected. I have the code below, but it’s not getting inside my #{contentEditorBacking.addNewsArticle}.

Does anyone know how i can get into the method when a selectOneRadio is clicked?

<p:panel header="News Article Title">
    <h:panelGrid columns="2">
        <h:outputLabel for="title" value="Title" style="font-weight: bold;"/>
        <p:inputText id="title" required="true" value="#{contentEditorBacking.newsTitle}" />
        <h:outputLabel value="Site" />
        <p:selectOneRadio value="#{contentEditorBacking.selectedNews}" layout="pageDirection" onchange="submit()">
            <f:selectItem itemLabel="Public" itemValue="Public" />
            <f:selectItem itemLabel="Member" itemValue="Member" />
        </p:selectOneRadio>
        <p:commandButton value="submit" action="#{contentEditorBacking.addNewsArticle}" />
    </h:panelGrid>
</p:panel>

Two problems:

• To intercept on “change” in radio buttons (and checkboxes) You need the click event instead.
• The <p:commandButton> is by default an ajax button which isn’t prepared for synchronous submits like as performed by JS submit().

Just use <p:ajax> instead so that the submit is performed by ajax. Note that you don’t need to specify the event attribute, it defaults to click already.

<p:selectOneRadio value="#{contentEditorBacking.selectedNews}" layout="pageDirection">
    <f:selectItem itemLabel="Public" itemValue="Public" />
    <f:selectItem itemLabel="Member" itemValue="Member" />
    <p:ajax listener="#{contentEditorBacking.addNewsArticle}" />
</p:selectOneRadio>
<p:commandButton value="submit" action="#{contentEditorBacking.addNewsArticle}" />

Update as per the comments, you seem to want to navigate to another page with a parameter. The addNewsArticle() method should then look like as follows so that it is compatible with both <p:ajax listener> and <p:commandButton action>.

public void addNewsArticle() throws IOException {
    ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
    ec.redirect(ec.getRequestContextPath() + "/next.xhtml?action=add");
}
