1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
11.
12.

private ArrayList items = new ArrayList();
private void fillList()
{
UISelectItem item = new UISelectItem();
item.setValue("1");
item.setItemLabel("AAA");
items.add(item);
item = new UISelectItem();
item.setValue("2");
item.setItemLabel("BBB");
items.add(item);
item.setValue("3");
item.setItemLabel("CCC");
items.add(item);
}
public void setItems(ArrayList items)
{
this .items = items;
}
public ArrayList getItems()
{
return items;
}
А вот фрагмент JSF-страницы, на которой установлено меню:
1.
2.
3.
4.
5.
6.

<body>
<h:form binding="#{backing_index.form}">
<h:selectOneMenu>
<f:selectItems value="#{backing_index.items}"/>
</h:selectOneMenu>
</h:form>
</body>
При запуске страницы выбрасывается исключение:
