Dear Bernd, Gerolf, Nino,
Thanks a lot for your replies: in two minutes I learnt a lot!
For my particular needs, wicket:enclosure is not the perfect solution:
I have several children,
<wicket:enclosure child='child1'>
<div wicket:id="child1"></div>
<div wicket:id="child2"></div>
</wicket:enclosure>
but using the child='...' syntax, the visibility is coupled to a
specific
child while I need child1.visible OR child2.visible OR ... .
So I'll go with Nino's setVisible(false) approach.
Thanks a lot for the feedback! Much appreciated. - Kaspar

hmm why do it complicated, just create a panel, and if your rules
decide it then call setvisible(false)... then no markup will be
visible from that component...

I have just started looking at Wicket and have a basic question.
My page displays an article with meta-data from the database. I
display the
meta-data in a box (a <div>...</div>). If no meta-information is
present,
I don't want the box (the <div>) to appear at all. Is there a
generic,
Wicket-style way for achieving this?
I struggle with two things here:
* How to do the conditional markup? (For instance, if the article
has no
author meta-information, I don't want to show "Authors: " in the
box.)
* How to avoid empty boxes? (The box component would have to
buffer its
markup and check, in the end, whether it is nothing but
whitespace.)
Thanks for any pointers.
Kaspar
