Unable to download the zip file after clicking confirmDialog ok button - jsf

Question

I am unable to download the zip file.
After clicking ok button in confirmDialog I am unable to download a zip file.
If I am not using confirmDialog I can able to download the file.
Could any one help me on this,
Here I added the code for the reference.
<h:form>
<p:panelGrid rendered="true">
<p:commandButton style="HEIGHT: 24px; WIDTH: 300px" id="AjaxFalse"
value="AjaxFalse"
action="#{testDownload.getZipFile}"
title="AjaxFalse" rendered="true">
<p:confirm message="Are you sure?"
header="Confirmation"
icon="ui-icon-alert" />
</p:commandButton>
</p:panelGrid>
<p:confirmDialog global="true" showEffect="fade" hideEffect="fade" width="500">
<h:panelGroup layout="block" style="text-align: center">
<p:commandButton value="Ok" type="submit" styleClass="ui-confirmdialog-yes" style="width:70px;"/>
<p:commandButton value="Cancel" type="button" styleClass="ui-confirmdialog-no" style="width:70px;"/>
</h:panelGroup>
</p:confirmDialog>
</h:form>
My backingbean is
public class TestDownload
{
//some code here
//Downloading the zip file in jsf2.x
public String getZipFile()
{
try{
//enter code here
FacesContext fc = FacesContext.getCurrentInstance();
ExternalContext ec = fc.getExternalContext();
ec.setResponseHeader("Content-Disposition", "attachment;filename=\"" + Test + ".zip\"");
ec.setResponseCharacterEncoding("UTF-8");
ec.setResponseContentType("application/zip");
//This method will generate the required file.
new BulkloadImporter().generateIntegrationXSDs(getId(), ec.getResponseOutputStream());
fc.responseComplete();
return "Save";
}
catch(Exception e)
{
//Handling exception
}
}
//some code here
}

This issue is not 'download' related. Up to now (PrimeFaces 5.3/5.3.2) using a <p:confirm...> global dialog in combination with ajax="false" does not work. The server side action in general will not be called.
There are two possible solutions:
Don't use global mode and do the download on the button in the confirmDialog
Use the workaround mentioned in the issue (not tested this myself)
An example of non-global usage can be found in the PrimeFaces Documentation (adapted to this case):
Getting started with ConfirmDialog ConfirmDialog has two modes; global and non-global. Non-Global mode is almost same as the dialog
component used with a simple client side api, show() and hide().
<h:form>
<p:commandButton type="button" onclick="PF('cd').show()" />
<p:confirmDialog message="Are you sure about downloading this file?"
header="Initiating download" severity="alert"
widgetVar="cd">
<p:commandButton value="Yes Sure" action="#{testDownload.getZipFile}" ajax="false"
update="messages" oncomplete="PF('cd').hide()"/>
<p:commandButton value="Not Yet" onclick="PF('cd').hide();" type="button" />
</p:confirmDialog>
</h:form>
