Primefaces How commandButton in Dialog Refresh datatable in parent page

Question

I need your help in refreshing the values in the datatable component after clicking on the commandButton in the dialog. The jsf code is:

<h:form id="Requests">
  <h:panelGroup id="table">
    <p:fieldset id="Pendings">
      <p:dataTable id="PendingRequests">
      </p:dataTable>
      <p:dialog header="cert1">
        <p:commandButton value="Print" id="Print" actionListener="#{msd.updatePrint}" />
      </p:dialog>
    </p:fieldset>
  </h:panelGroup>
</h:form>

The Print commandButton will fire a SQL UPDATE statement that will increment the count of the printing status in the database by 1. So if the value of the Printing Status column in the dataTable = 1, then this will increment by 1 and total will 2. Now, I want the dataTable in the parent page to pick up the change and to show that the Printing Status = 2.

I tried to add the below lines in the updatePrint() method but the increment is not shown in the dataTable:

public void updatePrint() {
//SQL UPDATE STATEMENT
    RequestContext context = RequestContext.getCurrentInstance();

    context.update(":Requests:Pendings:PendingRequests");
}

I tried also to use ajax but I wasn't success :

<p:dialog header="cert1">
  <p:ajax event="close" update=":Requests:Pendings:PendingRequests" />
</p:dialog>

you realy don't have any errors? Is your project running in JSF development mode? — Kukeltje, May 12 '15 at 13:50
Is there a way to refresh the datatable component on close of the dialog to refresh the dataTable or to call a javascript function to reload the parent page or the dataTable — 99maas, May 12 '15 at 14:02
Fix your ajax error handling (or learn to read server logs and response body). — BalusC, May 12 '15 at 14:19
