Description

I believe there is a enclosure related bug in wicket 1.4.2, which stopped me from upgrading Same code works fine with 1.4.1
Finally I narrowed it down to adding following to quick start (attached to problem):

2 lines to HomePage.html
<wicket:enclosure><br/><a wicket:id="logout"><wicket:message key="logout" /></a></wicket:enclosure>
<wicket:enclosure><a wicket:id="login"><wicket:message key="login" /></a></wicket:enclosure>

2 lines to HomePage.java
add(new BookmarkablePageLink<Void>("logout", HomePage.class));
add(new BookmarkablePageLink<Void>("login", HomePage.class));
and HomePage.properties
login=Login
logout=Logout

I get following stack trace

WicketMessage: Could not find child with id: login in the wicket:enclosure
