I sent this message to the user list, which seems to be more appropriated. But,
as I did not receive any answer, and since I saw some related questions without
answer, I'm sending this message to developers list. If it is a too big fault,
my apologies, I won't try this any more.

Hi, all!
I"m trying to use displaytag with external paging and sorting. I've implemented
the PaginatedList interface and trying to display an instance of that
implemented
class through the following code:
<display:table requestURI="autoridades.do?sender=btPaginar"
name="sessionScope.autoridades" class="padrao" sort="external" pagesize="10"
id="a" cellpadding="0" cellspacing="0" >
<display:column title="Autoridade" sortable="true" sortName="Autoridade"
headerClass="sortable">
${a.nome}
</display:column>
<display:column title="Cargo" sortable="true" sortName="Cargo"
headerClass="sortable">
${a.cargo}
</display:column>
<display:column title="Aniversário" sortable="true"
headerClass="sortable">
<c:if test="${a.diaAniversario > 0 && a.mesAniversario > 0}">
${a.diaAniversario}/${a.mesAniversario}
</c:if>
</display:column>
<display:column class="largura70" media="html" title=" "
headerClass="sortable">
<a href="javascript:
go(document.AutoridadesForm,'btVisualizar${a.codigo}')"><img
src="./images/5a.gif"
border="0" alt="Visualizar" /></a>
<a href="javascript:
go(document.AutoridadesForm,'btEditar${a.codigo}')"><img
src="./images/editar.gif" border="0" alt="Editar" /></a>
<a href="javascript:
go(document.AutoridadesForm,'btExcluir${a.codigo}')"><img
src="./images/cancelar.gif" border="0" alt="Excluir" /></a>
</display:column>
The table is displayed and paginations works fine, but sorting does not, as
the link when a column head is clicked does not contain "sort=name", rather
it shows a "sort=", an empty sort parameter, and without it it's not possible
to the application to figure out what criterion should be used to sort the list.
Does anyone has a sugestion about what is going on?
