I have an application with a logout button. After I doubleclick the button, I get a ViewExpiredException:
An unexpected exception was caught during processing the request:
javax.faces.application.ViewExpiredException: /faces/session-timeout.xhtml
My logout method has the following structure:
try {
destroyBackendSession(); // this logs to be successful
} catch (InvalidArgumentException e) {
logError(e);
} finally {
try {
FacesContext.getCurrentInstance().getExternalContext().redirect(userBean.getPortalUrl());
} catch (IOException e) {
logError(e);
}
FacesContext.getCurrentInstance().getExternalContext().invalidateSession();
}
No error is logged here, so it seems everything is working as expected here.
The bean is request scoped.
Potentially relevant config from my web.xml:
<context-param>
<!-- Serialization and deserialization of the component tree is a major performance hit. -->
<param-name>org.apache.myfaces.SERIALIZE_STATE_IN_SESSION</param-name>
<param-value>false</param-value>
</context-param>
[...]
<error-page>
<exception-type>javax.faces.application.ViewExpiredException</exception-type>
<location>/faces/session-timeout.xhtml</location>
</error-page>
Ideally, I would like to redirect the user to the portal page after logout, not an error page. (See userBean.getPortalUrl() in the logout()-method above)
