I meant, nest the Labels and Checkbox in the ListView that you nest in
the Form.

First a Form. The a ListView. And for each row a Label and a CheckBox
component? As the checkboxes paths are unique for each row, you should
have no problems there.
Doesn't that work for you?

Hi,
I'm currently trying to 'mirror' a quick & dirty JSP page in
Wicket & wondering how best do a particular thing...
I've got a list of Services, with basically a String ('name') and a
boolean attribute ('free'). There are 90-odd of these, and I need to
display them as checkboxes in a set of columns. The Q&D JSP method
puts them in a table, with a set of checkboxes making up a column in
a <td>...</td>, as below...
String generateServiceTable(List services, int colSize, String
listName) {
int cols = (services.size() / colSize) + 1;
StringBuffer sb = new StringBuffer();
sb.append("<table ><tr>\n");
int rows = 0;
for (int i = 0, ; i < services.size(); i++) {
Service service = (Service) services.get(i);
if (rows == 0) {
sb.append("<td valign=top width=\"" + 100 / cols +
"%\">\n");
}
rows++;
sb.append("<input type=\"checkbox\" name=\"" + listName +
"\" value=\"");
sb.append(service.getName());
sb.append("\"");
if (service.isFree()) {
sb.append(" checked");
}
sb.append(">");
sb.append(service.getName());
sb.append("<br>\n");
if (rows == colSize) {
sb.append("</td>\n");
rows = 0;
}
}
sb.append("</tr>\n");
sb.append("</table>\n");
return sb.toString();
}
so I get a
a1[] a11[] a21[] a31[] ...
a2[] a12[] a22[] a32[] ...
...
a10[] a20[] a30[] a40[] ...
effect, but I'm having difficulty working out a good/clean/simple way
of achieving the same result with Wicket.
(Note that using the same name on the checkboxes results in them
behaving in the same way as a multiple-choice list does, in terms of
what the browser dispatches, at least.)
I had this all working happily, using a ListMultipleChoice, so I've
got the 'surrounding' form/model, etc, it's just how best to do this
that's unclear...
