Try EmptyPanel component which is shipped with Wicket.
if (condition)
add(new YourVisibleComponent("componentId"));
else
add(new EmptyPanel("componentId"));
Do not forget about OOD. You can introduce createYourVisibleComponent()
method which creates empty panel in base class and some certain component in
derived classes.
