From the description of the tag
http://cwiki.apache.org/WICKET/wickets-xhtml-tags.html I think the 1.4.4
behavior would be correct, and if the example Vadim provided used to
work it would be due to a bug.
The attribute on the tag makes it clear it is a 'child' otherwise it
would have been named 'randomWicketId' :)
The tag is really a case of (limited) conditional markup which I think
we want the framework to stay away from. If there was a vote to expand
the behavior, then perhaps it should also move out of the core to wicket
extensions (if such a thing is possible).

hrm, already two people stumbled into this. i was of the mind that the
way it works now is the correct behavior, but i am starting to think
maybe i was incorrect...

all,
i just migrated to 1.4.4 from 1.4.3 and looks like enclosure functionality
changed. if enclosure doesn't have child element in it, it throws exception.
for example following code works in 1.4.3
...
<wicket:enclosure child="link">
<div>...</div>
</wicket:enclosure>
<a href="#" wicket:id="link">...</a>
...
but in 1.4.4 it throws exception (see below).
is 1.4.4 functionality correct or 1.4.3?
Thanks,
Vadim
