Ramon Casha commented on MYFACES-1121:
--------------------------------------
Ok here's what I did to fix it. Note that this is a duct tape solution.
Edit HtmlRendererUtils.java, function "public static String
selectContentType(String contentTypeListString)" (line 995 or thereabouts)
Replace the first bit with:
if (contentTypeListString == null)
{
FacesContext context = FacesContext.getCurrentInstance();
if(context == null) {
contentTypeListString = HTML_CONTENT_TYPE;
} else {
contentTypeListString = (String)
context.getExternalContext().getRequestHeaderMap().get("Accept");
if(contentTypeListString == null)
{
if (log.isDebugEnabled())
log.debug("No content type list given, creating
HtmlResponseWriterImpl with default content type.");
contentTypeListString = HTML_CONTENT_TYPE;
}
}
}
The main change is that if FacesContext.getCurrentContext() is null, it uses
the default content type too.

> FacesContext.getCurrentContext is null in the page following a successful
> login. The login is a standard JSP forms-based login. The form redirects to
> j_security_check as normal, then presumably it gets automatically redirected
> to the originally requested page. That's when the error occurs (see stack
> trace below). If I then refresh the page, it displays correctly.
