Timer, atualizar componente na tela nullPointer

Programação Java
#1

fiz o seguinte TIMER :slight_smile
porém esta dando nullPointer aqui

FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add(“formTeste:tableMonitorRealTimeXXXXX”);:

[CODE]
public void startTimer() {
timer = new Timer();
timer.schedule(new RemindTask(), 0, //initial delay
1 * 1000); //subsequent rate
}

 class RemindTask extends TimerTask {

	    public void run() {
	      if (executaTimer) {
	    	  log.info("YYYYYYYYYYYY START METHOD MONITOR REAL TIME YYYYYYYYYYYY");
	    	  criaListaMonitorRealTime();
	    	  
	      } else {
	        
	        timer.cancel(); //Not necessary because we call System.exit
	        
	        //System.exit(0); //Stops the AWT thread (and everything else)
	      }
	    }
	  }	

public void criaListaMonitorRealTime() {
       ......

FacesContext.getCurrentInstance().getPartialViewContext().getRenderIds().add(“formTeste:tableMonitorRealTimeXXXXX”);

<h:form id="formTeste">

<p:inputText id=“modeloVeiculo” value="#{monitorRealTimeMB.nome}" style=“text-transform:uppercase” />
