Greetings!
I have copied a custom component from "JavaServer Faces" by O'Reilly to
use in my myfaces application and I am getting ClassCastException
whenever I call "component.encodeBegin(context)": The following code is
what throws the ClassCastException:
Calling code:
UITabLabel tabLabel = (UITabLabel)child.getFacet("label");
encodeRecursive(context, tabLabel);
Called Method implementation:
private void encodeRecursive (FacesContext context, UIComponent
component) throws IOException {
if (!component.isRendered()) {
return;
}
//throws ClassCastException
component.encodeBegin (context);
if (component.getRendersChildren()) {
component.encodeChildren(context);
} else {
Iterator it = component.getChildren().iterator();
while (it.hasNext()) {
UIComponent child = (UIComponent)it.next();
encodeRecursive(context, child);
}
}
component.encodeEnd(context);
}
The following is the custom component from the Book:
public class UITabLabel extends UICommand {
public static final String COMPONENT_TYPE = "com.oim.faces.TabLabel";
public static final String COMPONENT_FAMILY = "javax.faces.Command";
public UITabLabel () {
super();
setRendererType ("javax.faces.Link");
}
public String getFamily () {
return COMPONENT_FAMILY;
}
public void broadcast (FacesEvent event) {
if (event instanceof ActionEvent) {
processAction((ActionEvent)event);
}
}
private void processAction (ActionEvent event) {
UIComponent panelTab = getParent();
UIComponent panelTabbedPane = panelTab.getParent();
Iterator it = panelTabbedPane.getChildren().iterator();
while (it.hasNext()) {
UIComponent panel = (UIComponent)it.next();
if (panel.equals(panelTab)) {
panel.setRendered(true);
} else {
panel.setRendered(false);
}
}
}
public MethodBinding getAction () {
return null;
}
public void setAction (MethodBinding action) {
throw new UnsupportedOperationException();
}
public MethodBinding getActionListener () {
return null;
}
public void addActionListener (ActionListener listener) {
throw new UnsupportedOperationException();
}
public ActionListener[] getActionListeners () {
return new ActionListener[0];
}
public void removeActionListener (ActionListener listener) {
throw new UnsupportedOperationException ();
}
}
Any Ideas?
