Are you running your widget on a Leopard developer seed or on Tiger?
In leopard, there is a change to the "content-type" HTTP request
header sent by XMLHttpRequest from a webkit-based application (like a
widget). This change has been made to match other browsers. In Tiger,
this value defaulted to "application/x-www-form-urlencoded", which is
appropriate for request bodies containing name=value&name=value pairs
(In other words, your typical web form post request). This is a
sensible default, but didn't match Firefox, IE, etc. In Leopard, this
header value defaults to "application/xml" which is appropriate for
request bodies containing XML documents. The case of posting an XML
document is much less common, but it's still much more important to
match the XMLHttpRequest implementation on other browsers for
compatibility.
So bottom line, If you are running a widget on Leopard that makes
post requests, you need to decide if you want to override the HTTP
content-type header value manually, especially if you are posting
name=value pairs. something like this will work:

Hi,
it's most definitely no javascript-error as when I try to send out
the post-request I get back a small html-document that contains
just some ttags and a text saying something about a "parsererror".
I almost believe it is an error-message generated by webkit or
whatever it is that is responding to the request. Though I don't
know what could have generated this error-message as I tried out a
few post-request-examples from the internet and did exactly what
they did for generating the request.
Greetings,
Stephan

what is giving you the parse error? javascript? or xmlhttprequest?

Hi all,
I'm new to this list but not to widget-programming in general.
And I'm from Germany, so my Englisch might sound a bit strange
sometimes.
So, does anybody know why a post-request using XmlHttpRequest
could result in a parsererror? Normal get-requests do work fine,
but post-request do not though I think I did everything required
including setting of headers for parameters like mime-type,
length of data that will be sent with the post-request and so on.
I am not sure if is a problem with the post-request itself or
maybe with the url I use (maybe the result isn't well-formed or
something so that might lead to an parsererror?
Btw, I get the same error if I disconnect the internet, so it
rather seems as if this is an error-message built into safari or
webkit, but even if, I still don't know what causes this error.
Greetings and thanks in advance,
Stephan Huebner
