Item12590: Certain exceptions are rendered twice

Priority: Urgent
Current State: Closed
Released In: 1.1.9
Target Release: patch
Applies To: Engine
Component: FoswikiEngine
Branches: Release01x01 trunk
Reported By: JanKrueger

Last Change By: GeorgeClark
Any EngineException triggered in individual UI classes (or other switchboard handlers) is sent to the UA by FoswikiUI using $Foswiki::engine->finalizeError. The same Response object is kept alive, though, and later sent to the UA again, this time by $Foswiki::engine->finalize. Since the first go already created headers, the Content-Length header does not match the size of the actual response body generated. In some cases the web server will strip off the superfluous body parts, in others it will retain them – some web servers might mess up the response completely.

This could be considered a bug in either FoswikiUI or FoswikiEngine. The least invasive fix is to change finalizeError so that it empties the response object – that way the later call to finalize will be a no-op.
