title: PrimeFaces commandButton calls action about half a minute later
body: <p>In my main page, I have a tool bar which contains some command buttons and links. Also I have a datatable that shows some vehicles data. The command buttons defined in the tool bar do not work properly. When I press the button, the action method is executed after 30-40 seconds later. What should be the cause of this problem?</p>
  
  <p>Here is the tool bar:</p>
  
  <pre><code>&lt;p:toolbar height="30" switchType="client"&gt;
      &lt;p:toolbarGroup align="left"&gt;
          &lt;p:commandButton value="#{general.refresh}" icon="ui-icon-refresh" style="font-size:11px;"
              action="#{mainPage.refreshPage}" update="vehicleTable" ajax="false"/&gt;  
          &lt;p:commandButton value="#{general.service}" icon="ui-icon-wrench" style="font-size:11px;"/&gt;
          &lt;p:commandButton value="#{general.customerPointsShort}" icon="ui-icon-pin-s" style="font-size:11px;"
                              title="#{general.customerPoints}"/&gt;
          &lt;p:commandButton value="#{general.filtering}" icon="ui-icon-search" style="font-size:11px;"/&gt;

          &lt;p:commandButton  title="#{general.showOnGoogleMap}" icon="googleLogo" style="font-size:11px;"/&gt;
      &lt;/p:toolbarGroup&gt;
      &lt;p:toolbarGroup  align="right"&gt;

      &lt;/p:toolbarGroup&gt;
  &lt;/p:toolbar&gt;
