Refresh region with poll

If you have a region in your fragment, in the polllistener method, you can refresh a región with refresh method and then you make a partialtarget in the component that envolves a region

yourBindingregion.refresh(FacesContext.getCurrentInstance());
AdfFacesContext.getCurrentInstance().addPartialTarget(getPg());

But remember put Refresh=”ifNeeded” in the taskFlow of this region
