What is wrong with this approach. I am getting a duplicate Component Id Issue
Code: Select all
<h:form>
<h:panelGrid columns="1">
<h:selectOneRadio binding="#{Bean.radio}">
<p:ajax event="change" update="menu"/>
</h:selectOneRadio>
<h:selectOneMenu id="menu" binding="#{Bean.menu}"/>
</h:panelGrid>
</h:form>Code: Select all
@javax.faces.bean.ManagedBean(name = "Bean")
@javax.faces.bean.SessionScoped
public class Bean {
HtmlSelectOneMenu menu = new HtmlSelectOneMenu();
HtmlSelectOneRadio radio = new HtmlSelectOneRadio();
public Bean() {
menu.getChildren().add(getMenuItemSet1());
radio.getChildren().add(getRadioItems());
radio.addValueChangeListener(new ValueChangeListener() {
public void processValueChange(ValueChangeEvent event) throws AbortProcessingException {
if (((String) event.getNewValue()).equalsIgnoreCase("One")) {
menu.getChildren().clear();
menu.getChildren().add(getMenuItemSet2());
} }
});
}
private UISelectItems getRadioItems() {
List tempList = new ArrayList();
UISelectItems uISelectItems = new UISelectItems();
tempList.add(new SelectItem("One"));
tempList.add(new SelectItem("Two"));
tempList.add(new SelectItem("Three"));
uISelectItems.setValue(tempList);
return uISelectItems;
}
private UISelectItems getMenuItemSet1() {
List tempList = new ArrayList();
UISelectItems uISelectItems = new UISelectItems();
tempList.add(new SelectItem("A"));
tempList.add(new SelectItem("B"));
uISelectItems.setValue(tempList);
return uISelectItems;
}
private UISelectItems getMenuItemSet2() {
List tempList = new ArrayList();
UISelectItems uISelectItems = new UISelectItems();
tempList.add(new SelectItem("C"));
tempList.add(new SelectItem("D"));
uISelectItems.setValue(tempList);
return uISelectItems;
}
public HtmlSelectOneMenu getMenu() {
return menu;
}
public void setMenu(HtmlSelectOneMenu menu) {
this.menu = menu;
}
public HtmlSelectOneRadio getRadio() {
return radio;
}
public void setRadio(HtmlSelectOneRadio radio) {
this.radio = radio;
}
}
