Major Description
Hi,
I recently upgraded to click 2.3.0-RC1 and now all of my components
that extent the AutoCompleteTextField class have stopped working in
Jetty (still works in Tomcat though). I don't believe this is Jetty's
fault. Here is the response header sent on an AJAX call. Note the
duplicate "charset" attribute. This header looks the same in tomcat
or Jetty, I think that Tomcat just handles incorrect headers more
robustly. I've tried adding a servlet filter reset the encoding type,
but that did not resolve the unsupported encoding error I see in
Jetty.
Cache-Control:no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Content-Type:text/html; charset=ISO-8859-1; charset=ISO-8859-1
Expires:Thu, 01 Jan 1970 00:00:00 GMT
Pragma:no-cache
Server:Jetty(7.2.0.v20101020)
Transfer-Encoding:chunked
All of this code worked fine with Click 2.2.0. Did something change
in the way headers are handled in Click between versions 2.2.0 and
2.3.0-RC1? Any Ideas?
Here is a copy of the stacktrace I am seeing in jetty:

I was able to resolve the issue by overriding AutoCompleteTextField#createBehavior
and commenting the line:
actionResult.setContentType(contentType);
