Fix Version: Nightly Build
Resolution: Fixed
> ExtensionFilter called multiple times under Weblogic
> ----------------------------------------------------
>
> Key: MYFACES-347
> URL: http://issues.apache.org/jira/browse/MYFACES-347
> Project: MyFaces
> Type: Bug
> Components: Tomahawk
> Versions: 1.0.9 beta
> Environment: Windows 2000 Server, Weblogic 8.1 SP2
> Reporter: Dan Zehme
> Assignee: Martin Marinschek
> Fix For: Nightly Build
>
> Because of a lack of clarity in some version of the serlvet specification,
> Weblogic, unlike Tomcat and JBoss, invoke the servlet filters not only on the
> initial request but on forwards and includes through the RequestDispatcher.
> This behavior causes the ExtensionFilter to be called multiple times for a
> single request causing multiple insertions of the header information or
> unnecessary errors indicating that no head or body was found.
> The solution to this problem is to set a request attribute indicating that
> the filter has been run and just calling chain.doFilter() when that request
> attribute is set.
