debugcn 投稿 Dev

Makku :

i need to get itemValue from <f:selectedItems>

this is my xhtml

<h:form>
<h:panelGrid columns="3" cellpadding="5"> 
    <p:outputLabel for="negara" value="Negara"></p:outputLabel>
    <p:selectOneMenu id="negara" value="#{propinsiBacking.countryID}">
        <f:selectItems value="#{propinsiBacking.listNegara}" var="negara" itemLabel="#{negara.countryName}" itemValue="#{negara.countryID}"></f:selectItems>
    </p:selectOneMenu>
    <p:commandButton value="Go" action="#{propinsiBacking.test}"></p:commandButton>
</h:panelGrid>
</h:form>

and my backingBean this is i get data from database

private List<NegaraEntity> listNegara;
private int countryID;
@PostConstruct
public void init()
{
    listNegara = negaraRules.getNegara();
}

and i want to get id from <f:selectedItem> so i sytem.out.println like this

public void test(int ctyId)
{
    ctyId = countryID;
    System.out.println(ctyId);
}

but this not working,any idea?

thanks for the help.

C.P.O :

The problem is the method public void test(int ctyId) because it have a param int ctyid

JSF must say: javax.el.MethodNotFoundException

Change to public void test() remember that apply request values phase occurs before invoke application phase, so #{propinsiBacking.countryID} is already set when method is executed.
