Leonardo Uribe resolved MYFACES-3174.
-------------------------------------

    Resolution: Invalid
      Assignee: Leonardo Uribe

I have checked it and the hack done by this component is invalid from spec point of view. 

The problem is JSF default ResponseWriter only handles html and xhtml, so it only accepts the following:

text/html
text/*
*/*
application/xhtml+xml
application/xml
text/xml

It is not surprising it does not accept text/css, because the default ResponseWriter  doesn't know how to handle such type. There are two options:

1. pass as second parameter for 
RenderKit.createResponseWriter(Writer writer, String contentTypeListString, String characterEncoding)

*/*, to ignore Accept header.

2. create a custom ResponseWriter for that content type and use it in a custom RenderKit.

see JSF 2.0 spec section 8.1:

"... The contentTypeList parameter is an "Accept header style" list of content types for this response, or null if the RenderKit should choose the best fit. [P1-start-contentTypeList]The RenderKit must support a value for the contentTypeList argument that comes straight from the Accept HTTP header, and therefore requires parsing according to the specification of the Accept ..."

I'll close this one as invalid.
