Redirect after p:remoteCommand not working

Question

I'm having problem with redirecting user to homepage after some action. I have searched stackoverflow and found many solutions, especially from @BalusC, but neither of them worked for me.

pageA - remoteCommand: 

<p:remoteCommand name="submit" process="@this" action="#{beanA.submitForm}"/>

pageA - submit button that calls modal dialog for signing content 

<p:commandButton value="Sign data" id="sign" actionListener="#{beanA.signData}" global="false" styleClass="button" />

After user click commandButton there is some data logic that is being run in bean, modal dialog is called with its own bean, and from there p:remoteCommand is called: 

RequestContext.getCurrentInstance().execute("submit()");    

String message = "Redirect successfuly done!";

FacesContext context = FacesContext.getCurrentInstance();
FacesMessage facesMessage = new FacesMessage(FacesMessage.SEVERITY_INFO, "INFO:" , message);

context.addMessage("form:h_m", facesMessage); // h:message on landing page waiting for message  

externalContext.getFlash().setKeepMessages(true);

return "/view.xhtml?faces-redirect=true&includeViewParams=true";

h:message in view.xhtml: 

<h:form id="form">  
 <div id="divs">
  <div id="top">
   <h:message id="h_m"/>    
    .....
    .....
  </div>
 </div>
</h:form>

Long story short - when user press the submit button (that calls dialog), modal dialog pops up, user click submit button again, there is some logic to be processed and then remoteCommand is called and pop up is closed. That's the moment when redirect should be done but nothing happens after pop up is closed, just error:

There is no action, I'm not sure why is URL null?

EDIT - CONFIGURATION:

Liferay 6.2 CE GA3
Primefaces 5.2
Liferay Faces 3.2.5-ga6

This is a bug in the way that the Liferay Faces Bridge does ajax redirects in the 3.2.5-ga6 (and most likely previous versions). I've opened a ticket for this ( FACES-2485 ). If possible, I recommend that you use a non-ajax redirect to workaround this issue. Simply add ajax="false" to whatever command component is calling your redirect: 

<p:commandButton action="#{bean.methodWithRedirect}" ajax="false" />

I am not sure if <p:remoteCommand> supports an URL as return value for action.

But you can always redirect programmatically like shown here:
