Minor Description
Just stubled upon BoxBorder, which is "A very simple border component that draws a thin black line around its children." and creates markup like this:
<table width = "0%" border = "0" cellspacing = "0" cellpadding = "1" bgcolor = "black">
<tr>
<td width = "100%" valign = "top">
<table width = "100%" border = "0" cellspacing = "0" cellpadding = "4" bgcolor = "white">
<tr>
<td width = "100%">
<wicket:body/>
</td>
</tr>
</table>
</td>
</tr>
</table>
I know, no one is forced to use it... but honestly: no developer should be lead to the assumption that creating a border like this is a good idea.
I suggest to deprecate it, or otherwise move it to wicket-extension or somewhere else.
