    a4j:poll doesn't rerender element

    Jonathan Andersson Newbie

      I'm trying to use the a4j:poll tag to update a section of a page. The ajax response contains the updated information(seen by using a4j:log) but the section isn't updated on the page.

      page;

       <a4j:log />
       <a4j:region id="dynamicRegion">
       <div id="dynamicData" class="infoBox">
       <div class="header"><span>#{messages['dynamicData']}</span></div>
       <s:fragment rendered="#{trip.dynamicVesselData ne null}">
       <div class="pack">
       <div class="label">#{messages['informationAge']}:</div>
       <div class="text">#{tripAction.informationAge}</div>
       </div>
       <div class="pack">
       <div class="label">#{messages['longitude']}:</div>
       <div class="text">#{tripAction.longitude}</div>
       </div>
       <div class="pack">
       <div class="label">#{messages['latitude']}:</div>
       <div class="text">#{tripAction.latitude}</div>
       </div>
       <div class="pack">
       <div class="label">#{messages['sog']}:</div>
       <div class="text">#{trip.dynamicVesselData.speedOverGround}</div>
       </div>
       <div class="pack">
       <div class="label">#{messages['cog']}:</div>
       <div class="text">#{trip.dynamicVesselData.courseOverGround}</div>
       </div>
       <div class="pack">
       <div class="label">#{messages['rot']}:</div>
       <div class="text">#{trip.dynamicVesselData.rateOfTurn}</div>
       </div>
       <div class="pack">
       <div class="label">#{messages['navigationalStatus']}:</div>
       <div class="text">#{trip.dynamicVesselData.navigationalStatus}</div>
       </div>
       </s:fragment></div>
       </a4j:region> <h:form>
       <a4j:region>
       <a4j:poll id="poll" action="#{tripAction.updateTrip}"
       interval="10000" reRender="dynamicRegion,:dynamicData"
       enabled="true" />
       </a4j:region>
       </h:form>

      which seams to be correct...

      Any ideas of what I'm doing wrong?

      using ajax4jsf-1.1.2-20070813.000131-165.jar
