I've found a way to check if a lifecycle is currently in process and to start a lifecycle if not. This seems to work well.

/**

• Navigate browser to a different page using an outcome argument to
• select the navigation rule. The mechanism for navigation depends on
• the navigation rule. <p>
  *
• If there is no JSF lifecycle in progress when this method is called,
• this method will manage one. Otherwise, it is the callers responsibility
• to call the <code>execute</code> method before, and <code>render</code> method
• after this navigation method.
  *
• @param outcome the 'from-outcome' field in the navigation rule.
  */
  public void navigateTo(String outcome) {
  warnIfSynchronous();
  try
  Unknown macro: { BridgeFacesContext facesContext = view.getFacesContext(); FacesContext fc = FacesContext.getCurrentInstance(); // #4251 start a lifecycle to re-establish the ViewRoot before // trying navigation if a lifecycle is not already running. if (fc == null) { execute(); } facesContext.getApplication().getNavigationHandler(). handleNavigation(facesContext, facesContext.getViewRoot().getViewId(), outcome); if (fc == null) { render(); } }

  catch (Exception e)

  { throw new RuntimeException(e); }

  }

I've removed the threadLocal management code in this method since it already is in place in the execute and render
methods.

I've tried updating a local copy of the ICEfaces source with this, and I'm still getting the NullPointerException. I added some calls to system.out to see what was going on....

public void navigateTo(String outcome) {
warnIfSynchronous();
try {
BridgeFacesContext facesContext = view.getFacesContext();
FacesContext fc = FacesContext.getCurrentInstance();
System.out.println("fc = " + fc);
if (fc != null)

// #4251 start a lifecycle to re-establish the ViewRoot before
// trying navigation if a lifecycle is not already running
if (fc == null)

facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, facesContext.getViewRoot().getViewId(), outcome);
if (fc == null)

} catch (Exception e)

}

When I look at the system log, I'm getting

core render service created:
core pool size : 10
max pool size : 15
keep alive time: 300000
fc = com.icesoft.faces.context.BridgeFacesContext@19b7f7f
fc.getViewRoot() = null

So this isn't working in my instance.

If I change the check to

if ((fc == null) || (fc.getViewRoot() == null)) {

It never completes (so the navigation never works).

From what I'm seeing, the BridgeFacesContext never goes away.

Hi. I've slightly changed the solution in order for it to work in my scenario:

public void navigateTo(String outcome) {
warnIfSynchronous();
try {
BridgeFacesContext facesContext = view.getFacesContext();
FacesContext fc = FacesContext.getCurrentInstance();
// #4251 start a lifecycle to re-establish the ViewRoot before
// trying navigation if a lifecycle is not already running
boolean manageLifecycle = ((fc == null) || (fc.getViewRoot() == null));
if (manageLifecycle)

facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, facesContext.getViewRoot().getViewId(), outcome);
if (manageLifecycle)

} catch (Exception e)

}

This works for my situation. All I've done is add an additional check for where the facesContext is not null, but the viewRoot is null.

I've changed the code to the customers example.
