Exception when redirect page

Question

Hi
I create a class implements PhaseListener
In afterPhase method I use FacesContext of ADF for redirect page as follow:
public void afterPhase(PhaseEvent phaseEvent) {
PhaseId phaseId = phaseEvent.getPhaseId();
FacesContext facesContext = phaseEvent.getFacesContext();
String url = ....;
try {
facesContext.getExternalContext().redirect(url);
} catch (IOException ioe) {
But I see "java.lang.IllegalStateException: Response already committed"
I do not know why?
Please help me

Hi,
You can try this code instead of facesContext.getExternalContext().redirect(url);
HttpServletResponse response = (HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse();
response.sendRedirect(url);
FacesContext.getCurrentInstance().responseComplete();Hope this helps
