> Hello,
> When a backing bean throws an Exception (HibernateException in our case), instead of being redirected to the error page declared in web.xml, we end up with the default Tomcat 500 error page.
> This is due to a a ViewExpiredException that is triggered while the system attempts to perform the Restore View JSF phase for the page with view id "/500.xhtml".
> Here is the stack trace from the Tomcat log:

> Here is what we found from our investigation.
> When submitting a login form from page "/login.xhtml", our code triggers a HibernateException. This generates a 500 error.
> Then, in org.apache.myfaces.lifecycle.RestoreViewExecutor#execute, when reaching the Restore View JSF phase for view id "/500.xhtml", restoreViewSupport.isPostback(facesContext) is true, and thus, thinking this is a postback situation (which is weird as we are moving to a different page, the error one), the system attempts to restore a viewroot using the current view state.
> The problem is, there is no existing view state in the session for view id "/500.xhtml" -- there is only state for the page we are coming from and which triggered the HibernateException, "/login.xhtml" (the view state is searched / computed in org.ajax4jsf.application.AjaxStateManager#restoreView). So the viewRoot returned by viewHandler.restoreView(facesContext, viewId) is null, and a ViewExpiredException is thrown. The default Tomcat error page is then shown.
> // Determine if this request is a postback or initial request
> if (restoreViewSupport.isPostback(facesContext))
> {
> if (log.isTraceEnabled())
> log.trace("Request is a postback");
> viewRoot = viewHandler.restoreView(facesContext, viewId);
> if (viewRoot == null)
> {
> throw new ViewExpiredException("The expected view was not returned " + "for the view identifier: "
> + viewId, viewId);
> }
> restoreViewSupport.processComponentBinding(facesContext, viewRoot);
> }
> else
