Igor Vaynberg resolved WICKET-2605.
-----------------------------------

    Resolution: Won't Fix

this usecase is a little crazy. you are relying on the fact that if the parent is invisible you can have components in the parent's markup that have no java counterparts. this *happens* to work for normal rendering, but by no means is by design.

if you want to continue to rely on this non-feature you can simply replace the enclosure with a webmarkupcontainer.

> 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
> Root cause:
> org.apache.wicket.WicketRuntimeException: Could not find child with id: login in the wicket:enclosure
