[Xsltforms-support] XHR response error for non-XML content types

[Tim T. <tim...@gm...>]

Alain,

I'm testing XSLTForms on an Apache XAMPP server (though not yet with
SaxonHE9-4-0-7), and I had (another) question about browser errors.

Here's a Gist that shows a basic submission from XSLTForms to DBpedia's
SPARQL endpoint, using @replace="text" on the <xf:submission> element:
https://gist.github.com/Timathom/176a1e6865215b00d544

This works beautifully, but in Firefox and IE 11, I am getting browser
errors on the XHR response.

Here is the HTTP response header in Firefox:

HTTP/1.1 200 OK
Date: Fri, 10 Jul 2015 13:26:30 GMT
Content-Type: application/ld+json
Content-Length: 7127
Connection: keep-alive
Server: Virtuoso/07.20.3214 (Linux) i686-generic-linux-glibc212-64  VDB
Access-Control-Allow-Origin: http://localhost
access-control-allow-credentials: true
access-control-expose-headers: Content-Type
Access-Control-Allow-Headers: Accept, Authorization, Slug, Link, Origin,
Content-type
Expires: Fri, 17 Jul 2015 13:26:30 GMT
Cache-Control: max-age=604800
Accept-Ranges: bytes

Even though the server returns a Content-Type of "application/ld+json," the
browser still tries to parse it as XML. Firefox throws this error (via
Firebug):

XML Parsing Error: not well-formed Location:
moz-nullprincipal:{a25b11dd-9e4b-5f40-bb8b-b9415ed8d56e} Line Number 1,
Column 1:

{ "@graph": [
^

IE 11 throws this error:

XML5619: Incorrect document syntax. Line: 1, Column 1

Chrome does not throw a (visible) error. I guess that these errors are
probably harmless, but is there any way to avoid them, and to prevent the
browser from trying to parse the response as XML when the XForms submission
has a @replace attribute value of "text" and the Content-Type of the
response is a non-XML format?

Thanks again!
Tim

Tim,

Currently, XSLTForms is not interpreting media type correctly: the 
response media type has to be analyzed instead of submission/@mediatype 
which is there just for the request serialization. I tested adding the 
overrideMimeType property to the request and the browser errors don't 
occur anymore!

I will fix this as soon as possible.

Thanks!
