How to invoke task flow navigation after closing inline popup?

Question

Using JDev 11.1.1.3; I have a commandButton that currently executes task flow navigation when pressed. I need however to invoke an inline popup from the button press before executing (conditionally) the task flow navigation. The Action setting on the button then needs to be removed, but it's not clear where to reinstate it. I have the button executing some managed bean code, which conditionally invokes the inline popup, and when the popup (contains af:dialog) is closed, I have some more managed bean code that determines whether the task flow navigation should occur or not. What I need to know is how to fire off the Action from the managed bean. Any suggestions?
Thanks,

1. To add to Timo's solution:
you can call those code from DialogListener like:
public void dLstnr(DialogEvent dle){
if("ok".equalsIgnoreCase(dle.getOutcome().toString())){
FacesContext context = FacesContext.getCurrentInstance();
NavigationHandler nh = context.getApplication().getNavigationHandler();
System.out.println("1");
nh.handleNavigation(context, "", "go");
2. As another solution:'
you can have custom buttons and on one of then (say OK or Yes) you can call bean method like this as Action:
public String actionMethod(){
// DO YOUR LOGIC
return "NEXT_TARGET";
for Other button (say Cancel, NO) just close the popup.
