[jira] Commented: (COCOON-2150) Error on resetting response

["Jörg Heinicke (JIRA)" <ji...@apache.org>]

Jörg Heinicke commented on COCOON-2150:
---------------------------------------

Reinhard mentioned the suspicion about the error handler: http://marc.info/?l=xml-cocoon-dev&m=119582926910325&w=4.
I can confirm it in my case (http://marc.info/?t=119580475700001&r=1&w=4) since I got a proper error message returned to the browser (i.e. response was sent by error handler).

> It seems to be thrown whenever the response object is reseted after the actual response has been sent by the sitemap error handler. In this case reset is no longer possible since the response has already been committed as stated in the error message.
