one more on that.
The rows="10" ensures that you only see 10 items on a page. IF you have more,
paging is done for you, without any other scroller or so. :)

Trent,
have you ever checked Trinidad's <tr:table> ?
It is pretty much straight forward to do a selection there:
<tr:table summary="Bundeslaender"
value="#{lov.data}" var="row" rows="10"
rowSelection="single"
binding="#{lov.table}">
<tr:column>
<f:facet name="header">
<tr:outputText value="Name"/>
</f:facet>
<tr:outputText value="#{row.name}"/>
</tr:column>
</tr:table>
<tr:panelButtonBar>
<tr:commandButton text="Cancel" immediate="true"
action="#{lov.cancel}"/>
<tr:commandButton text="Select"
action="#{lov.select}"/>
</tr:panelButtonBar>
in the select you do:
public String select()
{
FacesContext context = FacesContext.getCurrentInstance();
Iterator<Object> iterator = _table.getSelectedRowKeys().iterator();
String rowKey = (String) iterator.next();
Object oldRowKey = _table.getRowKey();
_table.setRowKey(rowKey);
ValueBinding binding = context.getApplication().
createValueBinding("#{row.name}");
Object value = binding.getValue(context);
RequestContext.getCurrentInstance().returnFromDialog(value, null);
_table.setRowKey(oldRowKey);
return null;
}
note you can also set the "rowSelection" to multiple.
See [1] for more.
