ajax - Redirecting with return statement influences the rendering process in next page -


i have problem rendering of datatable. in application have navigation bar:

<h:form>     <ul class="nav nav-tabs">          <li class="active" role="presentation">             <h:commandlink value="veranstaltungen" action="#{eventcontroller.redirect('veranstaltung.xhtml')}"/>         </li>                                <li role="presentation">              <h:commandlink value="beacons" action="#{beaconcontroller.redirect('beacon.xhtml')}"/>         </li>           [...]              </ul> </h:form>

redirect (beaconcontroller):

public string redirect(string link) {     beacons = database.getallbeacons();     return "./" + link; }

the navigation works perfectly, when submit form beacondata in beacon.xhtml datatable won't rendered.

<h:form id="beaconstable">     <p:datatable value="#{beaconcontroller.beacons}" var="b"         tablestyleclass="table table-striped"         emptymessage="keine beacons verfügbar"         style="font-size:14px"         rowindexvar="rowindex"         rowstyleclass="#{(rowindex mod 2) eq 0 ? 'first-row' : 'second-row'}"         >         <p:column style="float:left;border:none;">             <f:facet name="header">                    <h:commandlink actionlistener="#{beaconcontroller.sortbeacons}">                           <f:ajax execute="@this" render="beaconstable"/>                          beacons                     </h:commandlink>                 </f:facet>             <h:commandlink>                  <f:ajax listener="#{beaconcontroller.fillfields(b)}" execute="@this" render=":beacondata beaconstable :delete"/>                  <h:outputtext value="#{beaconcontroller.getcompletestring(b)}" style="#{beaconcontroller.currentbeacon == b ? 'color:#337ab7' : 'color:#555555'}"></h:outputtext>             </h:commandlink>         </p:column>     </p:datatable> </h:form>   </div> <div class="col-lg-6">     <h:form role="form" id="beacondata" enctype="multipart/form-data">         <div class="form-group">             <label>uuid*</label>             <h:inputtext id="id_uuid" binding="#{uuidattribute}" class="form-control" value="#{beaconcontroller.uuid}" p:placeholder="unternehmen" required="true" requiredmessage="bitte uuid angeben" validatormessage="bitte nur zahlen und buchstaben angeben">                 <f:validateregex pattern="[0-9a-za-z]+"/>             </h:inputtext>             <h:message styleclass="errmessage" for="id_uuid" style="color: red"/>         </div>         [...]                           <h:commandbutton type="submit" value="speichern" actionlistener="#{beaconcontroller.savedata}" class="btn btn-primary" disabled="#{beaconcontroller.currentbeacon == null}">             <f:ajax render="beacondata :beaconstable" execute="@form"/>         </h:commandbutton>     </h:form> </div>

clicking on other entry in datatable, solves problem. table rendered on submit. why dosen't work on first time?

when change action="#{beaconcontroller.redirect('beacon.xhtml')}" in navigation bar action="beacon.xhtml" works correct. thought these expressions meaning same?
