Answer 1

As mentioned by BylusC, deployment descriptor must not contain any error-page handler that will catch ViewExpiredException (wrapped inside ServletException) instead of the correct one - error-page for ViewExpiredException.

Do not forget to verify that server's deployment descriptor (e.g. TomEE/conf/web.xml) does not contain java.lang.Throwable or java.lang.Exception error-page definitions. Because these two web.xml are basically merged.

Yes - application's web.xml has precedence over server's web.xml, but if application's web.xml contains

• error-page for 500 (/error.xhtml)

and server's web.xml for

• 500 (/500.html) and for
• Throwable (/bigerror.html)

then application context will contain merge of those two:

• 500 (/error.xhtml)
• Throwable (/bigerror.html)

and ViewExpiredExcpetion error handling will not work correctly.
