Hello Yannick, I just don't get it right.
colPersonas is the full collection of 21.000 items and tamanioColeccion
is it's size. Both attributes are in sessionScope, colPersonas is seen
by displayTag under the name attribute, what should I do with that
partial list matching the pagesize number you told me about? How do I
get it?
Thanks again!
Pablo.

Is your colPersonas the full collection of 21.000 items ? In this
case, the size attribute is just right, but you have to give a partial
list (name attribute), meaning a collection with size normally
matching the pagesize number.

Yes, I have already tried that as follows:
This are the involved lines in my Struts Action:
sessionManager.setAttribute("colPersonas", colPersonas); // the
collection obtaind via mysql query.
sessionManager.setAttribute("tamanioColeccion", new
Integer(colPersonas.size())); // collection's size in session scope.
This is the new display:table tag in the JSP:
<display:table class="display" excludedParams="*"
id="adm.busquedaPersona.colPersonas" pagesize="20"
name="sessionScope.colPersonas" sort="external" partialList="true"
size="sessionScope.tamanioColeccion" requestURI="busquedaPersona.do"
style="width:98%"
decorator="conicet.apps.eva.web.administrador.decorator.CBusquedaPersonaWrapper">
But it gets hung, like loading the page that never appears... am I missing
something?
Thanks!
Pablo.

Hi Pablo,
You should really consider using/implementing external paging...

Hello, I have a collection of about 21.000 rows to display via display
tag. It's taking displaytag about 2 minutes to render the page (first
time it's loaded), is there any way to make this better? I'm using
displaytag 1.1.
Here's the JSP code:
<display:table class="display" excludedParams="*"
id="adm.busquedaPersona.colPersonas" pagesize="20"
name="sessionScope.colPersonas" requestURI="busquedaPersona.do"
style="width:98%"
decorator="administrador.decorator.CBusquedaPersonaWrapper">
<display:setProperty name="paging.banner.placement" value="both"/>
<display:column property="categoriaW" title="Categoría"
sortable="true" style="align:center"/>
<display:column property="legajoW" title="Legajo"
sortable="true" style="align:center"/>
<display:column property="nomapW" title="Apellido y Nombre"
sortable="true" style="align:center"/>
<display:column property="tipoNroDocW" title="Tipo y Nro Doc."
sortable="true" style="align:center"/>
<display:column property="cuilW" title="Cuil" sortable="true"
style="align:center"/>
<display:column property="estadoW" title="Estado"
sortable="true" style="align:center"/>
<display:column property="verW" title="Ver" sortable="false"
style="align:center"/>
</display:table>
Thanks in advance!
Pablo.
