    Updating <rich:dataScroller> after <a4j:support> request

    Daniel Behrwind Newbie

      Hi,


      I'm implementing a forum using Seam, rich:dataTable and rich:dataScroller pretty much the same way as described here: http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4112998


      My forum allows categorizing topics and provides a h:selectOneMenu to filter topics by their categories. Basically it works like this: The user selects an item from the h:selectOneMenu, which causes an ajax request, updating the content of the rich:dataTable that provides the topics.


      The problem is however that the dataTable's dataScroller gets updated before the new value of the selectOneMenu is applied, which results in a flawed presentation of the number of rows (it always displays the quantity for the previously selected category).


      Here's the JSF code:


      <div> 
      show topics: 
           <h:selectOneMenu value="#{forumEntryFilter.selectedCategory}">
                   <s:selectItems value="#{forumEntryFilter.categories}" var="category" label="#{category}" />
                   <a:support event="onchange" reRender="forumList" />
           </h:selectOneMenu>               
      </div>
                     
      <rich:dataTable value="#{forumEntryDataModel}" var="topic" rows="20" id="forumList">
                     
           <rich:column style="width: 70%;">
                ...
           </rich:column>
                          
           <rich:column style="width: 30%;">
                ...
           </rich:column>
                          
           <f:facet name="footer">
                <rich:datascroller id="scroller" />
           </f:facet>
                     
      </rich:dataTable>



      Any help is appreciated!
