Can you give me a help about how to use displaytag in my portal?

I'm having a problem with the URL created by the displaytag when i use the option pagesize.

Here is the code:

<c:set var="addRowURL">
 <portlet:actionURL portletMode="view">
 </portlet:actionURL>
</c:set>


<div id="hf-portlet-form-content">
<form name="ActionListShort" method="post" action="${addRowURL}">
<input type="hidden" name="<%= GeneralPortalConstants.PARAMETER__ACTION %>" value="" />
<input type="hidden" name="<%= GeneralPortalConstants.PARAMETER__CORE_ACTION_ID %>" value="-1" />

<c:set var="listaVal" value="<%= actionList %>"></c:set>
<table with="100%" cellpadding="0" cellspacing="0" class="portlet-form-input-field">
 <tr>
 <td align="center">
 <display:table name="${listaVal}" id="item" sort="list" style="width:100%; text-align:center" cellpadding="0" cellspacing="0" class="bem-theme.css" pagesize="2">
 <display:column sortable="true" property="startDateTimeFormat" title="${n:i18n('label.event.action.start_date')}" headerClass="sortable" class="portlet-form-input-field"/>

 <display:setProperty name="paging.banner.one_item_found" value=""></display:setProperty>
 <display:setProperty name="paging.banner.some_items_found" value=""></display:setProperty>
 <display:setProperty name="paging.banner.all_items_found" value=""></display:setProperty>

 </display:table>
 </td>
 </tr>
</table>
</form>
</div>

This produces me the URL: http://localhost:8080/bem/ActionList.jsp?d-49489-p=2

who isn't correct. The URL for this portlet is:

http://localhost:8080/portal/auth/portal/sigo/Accoes

I've also tried with requestURI:

 <display:table name="${listaVal}" id="item" sort="list" style="width:100%; text-align:center" cellpadding="0" cellspacing="0" class="bem-theme.css" pagesize="2" requestURI="${addRowURL}">

but it doesn't work.


Any help?

Thanks,
Pedro
