I am become crazy with wicket:enclosure to prevent an runtime error in case the
ListView is empty.
this is part of my html code:
<table border="1">
<wicket:enclosure child="cart:prezzo">
<tr wicket:id="cart">
<td><a href="#" wicket:id="OggettoLink" target="_blank"> <img
wicket:id="OggettoIcon" width="180" src="#" title="Apri in nuova finestra"
alt="Immagine"/> </a></td>
<td> <a wicket:id="titolo" href="#">Link</a></td>
<td wicket:id="prezzo">prezzo</td>
<td> </td>
</tr>
</wicket:enclosure>
</table>
----------------------------------
I use Wicket 6 beta. If you need more code, I can post it.
I try to change the child to:
cart
prezzo
OggettoLink
OggettoIcon
titolo
but I got always the same runtime error:
Unexpected RuntimeException
Last cause: Could not find child with id: cart:prezzo in the wicket:enclosure
Stacktrace
Root cause:
org.apache.wicket.WicketRuntimeException: Could not find child with id:
