Re: How to reference a component?

[Bruno Aranda]

Well, in the latest release (at least) you can find the extended
selectOneListbox. Have you declared the taglib in the beginning of
your jsp? Like this:

<%@ taglib uri="http://myfaces.apache.org/extensions"; prefix="x"%>

But, if you want to keep with the standard selectOneListbox and
although I don't understand which is the objective of what you are
trying to do, here we go!

- Step1: Create a backing bean with this code, where there are two
selectOneListbox components declared (the ones we need):

[CODE]

import javax.faces.component.html.HtmlSelectOneListbox;
import javax.faces.context.FacesContext;

public class ConfigurationTest extends BioexedraBeanBase{

    private HtmlSelectOneListbox list1;
    private HtmlSelectOneListbox list2;

    public ListTestBacking() {
        list1 = new HtmlSelectOneListbox();
        list2 = new HtmlSelectOneListbox();
        
        // I assign an id to each list
        list1.setId("leftList");
        list2.setId("rightList");
        
        // here I assign the title for the list1, using the clientId
of the list2
        list1.setTitle(list2.getClientId(FacesContext.getCurrentInstance()));
        }
        

    public HtmlSelectOneListbox getList1() {
        return list1;
    }

    public void setList1(HtmlSelectOneListbox list1) {
        this.list1 = list1;
    }

    public HtmlSelectOneListbox getList2() {
        return list2;
    }

    public void setList2(HtmlSelectOneListbox list2) {
        this.list2 = list2;
    }

[/CODE]

- Step 2: now your jsp page must have the two selectOneListbox
components binded to the backing bean (using the 'binding' attribute
that every component has and which allows to bind the jsp component
with its instance declared in the backing bean):

[CODE]

<h:selectOneListbox binding="#{configurationTest.list1}">
        <f:selectItem itemValue="1" itemLabel="LeftItem1"/>
        <f:selectItem itemValue="2" itemLabel="LeftItem2"/>
</h:selectOneListbox>

<h:selectOneListbox binding="#{configurationTest.list2}">
        <f:selectItem itemValue="3" itemLabel="LeftItem1"/>
        <f:selectItem itemValue="4" itemLabel="LeftItem2"/>
</h:selectOneListbox>

[/CODE]

Then only remains to test it ;-)

If you have more doubts, don't hesitate to ask,
