Leonardo Uribe commented on MYFACES-2979:
-----------------------------------------
Ok, but anyway it is caused by an unexpected EL evaluation. In that case,
DebugPhaseListener should swallow the exception and let code continue, so maybe
we need to add some code in that part. Instead use visit tree hint for skip
unrendered, why don't check for that condition on DebugVisitCallback, so if we
can't evaluate it we can decide if we include it or not? Since this feature is
not intended for production, it is not a problem to do some additional cycles.

> Affects Versions: 2.0.3-SNAPSHOT
> Environment: MyFaces 2.0.3-SNAPSHOT in Dev mode, OpenWebBeans 1.0.0,
> Tomcat 6.0.29 (with Glassfish EL 2.2)
> Reporter: Jan-Kees van Andel

> I have a logout method, shown below:
> public String logout() {
> final FacesContext fc = FacesContext.getCurrentInstance();
> final ExternalContext externalContext = fc.getExternalContext();
> try {
> externalContext.invalidateSession();
> externalContext.redirect("http://www.google.nl";);
> } catch (IOException e) {
> log.error("Error redirecting after logout", e);
> } finally {
> fc.responseComplete();
> }
> return null;
> }
> When I invoke this method, I get the following Exception from OpenWebBeans:

> This happens because the DebugPhaseListener starts visiting the tree and, in
> the process, needs to resolve a value expression, which points to an OWB
> session bean.
> It only happens when the DebugPhaseListener is installed. In production mode
> everything is fine.
