personally I'm no fan of conditional adding components with the same id.
e.g.
if (user.isSignedIn() {
add(new SignedInPanel("foo"));
else {
add(new SignedOutPanel("foo"));
}
I rather add all panels and make them invisible or visible
add(new SignedInPanel("foo").setVisible(user.isSignedIn()); // or override
isvisible if that may change ...
add(new SignedOutPanel("bar").setVisible(!user.isSignedIn());
this way you always know which panels are added to the page and what they
are ...
regards,
