*Hey,
I have the following facelets code for display a selectbox:*
<h:selectOneMenu value="#{titleListManager.selectedTitle}">
<f:selectItems value="#{titleListManager.titleItems}" />
</h:selectOneMenu>
public <List>SelectItem getTitleItems() {
List<SelectItem> titleItems = new ArrayList<SelectItem>();
titleItems.add(new SelectItem("1", "1"));
titleItems.add(new SelectItem("2", "2"));
titleItems.add(new SelectItem("3", "3"));
titleItems.add(new SelectItem("4", "4"));
titleItems.add(new SelectItem("5", "5"));
return titleItems;
}
*Unfortunately, I get the exception below:*
java.lang.IllegalArgumentException: Expected a child component type of
UISelectItem/UISelectItems for component type
javax.faces.SelectOne(j_id273). Found null.
