you dont have to attach the listview to the trs though
in 1.2.6
you can attach it to span and do dataview.newitem(..) { return super.newitem
(..).setrenderbodyonly(true);
<table>
<span wicket:id="groupView"> <--- Outer listview
<tr>
<td wicket:id="groupTitle"></td>
</tr>
<span wicket:id="dataView"> <--- Inner listview
<tr>
<td wicket:id="data"></td>
</tr>
</span>
</span>
</table>
in 1.3 we have a placeholder that makes this easier
<table>
<wicket:container wicket:id="groupView"> <--- Outer listview
<tr>
<td wicket:id="groupTitle"></td>
</tr>
<wicket:container wicket:id="dataView"> <--- Inner
listview
<tr>
<td wicket:id="data"></td>
</tr>
</wicket:container>
</wicket:container>
</table>
advantage of wicket:container is that it will validate markup even at design
time, and it is stripped when strip-wicket-tags option is enabled.
rarely you do hit these cases where doing this in a jsp is easier because
the jsp renders top-down, but in my experience they are few and far in
between. and more importantly we have solutions to make them work.

Igor,
Upon further thought, how can a ListView inside a ListView solve this?
Wouldn't the hierarchy cause the html to be messed up? I can't have
TRs within TRs. The inner listview isn't putting child data inside of
the TR, it needs to make TRs that are siblings of the outer listview.
The output should be like this:
<table>
<tr wicket:id="groupView"> <--- Outer listview
<td wicket:id="groupTitle"></td>
</tr>
<tr wicket:id="dataView"> <--- Inner listview
<td wicket:id="data"></td>
</tr>
</table>
Not like this:
<table>
<tr wicket:id="groupView"> <--- Outer listview
<td wicket:id="groupTitle"></td>
<tr wicket:id="dataView"> <--- Inner listview
<td wicket:id="data"></td>
</tr>
</tr>
</table>
What am I not getting?
Thanks,
Tauren
