Http Error Page configuration causing Closing the buffer error

[Nishant Neeraj <ni...@gmail.com>]

Hi,

I have configured http error pages as per
this<https://cwiki.apache.org/WICKET/error-pages-and-feedback-messages.html>[1]
document. It works fine except I see "closing the buffer error" NPE
[2](see the stack trace below), on almost all the pages.

Removing
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>ERROR</dispatcher>
from wicket-filter tag stops the error but then error pages would not work.

Using wicket 1.4.9.
