Question

VIEW

<h:form id="main_form">
    <p:inputText id="title" required="true" label="Title" value="#{myBean.myLink.title}" immediate="true" />

    <p:selectOneMenu id="scope" required="true" label="Scope" value="#{myBean.myLink.scope}" immediate="true" >
        <f:selectItem itemLabel="Please choose" itemValue="" />
        <f:selectItems value="#{myBean.availableScopes}" id="selScope"/>
    </p:selectOneMenu>

    <p:inputText id="link" required="true" label="URL" value="#{myBean.myLink.link}" immediate="true">      
        <p:ajax event="blur" update="msgLink" listener="#{myBean.checkUrl}" />
    </p:inputText>

    ... msgLink and other (required) elements

    ... submit button
</h:form>

Managed Bean

@Component("myBean")
@Scope("session")
public class MyBean implements Serializable {

    private Link myLink;
    private Map<String, String> availableScopes;

    public MyBean() {
        this.availableScopes = new HashMap<String, String>();
        this.availableScopes.put("Intranet", "Intranet");
        this.availableScopes.put("Internet", "Internet");   
    }

    // setter/getters etc.

    public void checkUrl() {
        System.out.println(myLink.getTitle());  // works
        System.out.println(myLink.getScope());  // DOES NOT work
        System.out.println(myLink.getLink());   // works
    }

}

• I want to check the URL depending of the selected scope before submitting the form. But the called method can access the inputText values of the object. Not the value chosen in selectOneMenu.
• I have tried it with getExternalContext().getSessionMap().get("scope") but the SessionMap is null at that time.

Any chance to access the selected value of the combo box?

Thanks
Jim

Answer 1

The <p:ajax> (and <f:ajax>) inside an UIInput component executes/processes by default the current UIInput component (@this) only, not others.

If you want to execute/process all those UIInput components when the listener method is to be invoked, then you should specify that as such in <p:ajax process> (or <f:ajax execute>) attribute:

<p:inputText id="title" ... />

<p:selectOneMenu id="scope" ... >
    ...
</p:selectOneMenu>

<p:inputText id="link" ...>      
    <p:ajax process="title scope link" ... />
</p:inputText>

Unrelated to the concrete problem, I wonder how all those immediate="true" attributes are useful in this context. Are you certain you need them?
