Werner Punz commented on MYFACES-1682:
--------------------------------------
According to Matthias Wessendorf this is a Tomcat only thing and only if JSP as
renderer is used.
I could reproduce it on a Tomcat 6.0.13 in JSP mode, with facelets which do not
go into JSP everything works as expected.
My personal guess, and this is a guess, is that the dependency into the jstl
has anything to do with it in combination with other serveral sideffects.
Facelets eliminates the jstl dependencies and jasper, so it is very likely that
one of the two components do trigger this for whatever reason.
