Rails spinoffs - Sep 2007 - Ajax.request transport.responseText in IE7 unknown

Hi,

I am trying to run this code:
  function registerChallenge() {
    var postBodyVars
''loginName=''+document.getElementById(''name'').value;
    new Ajax.Request(''ajaxRegisterChallenge.php'', {
      method: ''post'',
      postBody: postBodyVars,
      onSuccess: function(transport) {
          alert(''test'');
          alert(transport.responseText);
        }
      },
      onFailure: function(request) {
      }
    });
  }

In ajaxRegisterChallenge.php I echo only a string. In FF and OP it
works great but in IE7 the type of the transport.responseText is
unknow and than the process stops.
I checked with HTTP Debugger if something with the response is wrong
but all ok.
I am using the current stable version of prototype.

Moreover the transport.statusText returns OK.

Thx for your help

I am replying to myself:

After adding:
  onException: function(req,exception) {
        alert("The request had a fatal exception thrown.\n\n" +
        exception);
        alert("exception.description:"+exception.description);
        alert("exception.message"+exception.message);
        return true;
      },
to the request IE7 told me about could not complete the operation due
to error c00ce56e.

After I asked google about that error I found the solution:
In the PHP file I have to add the following:

header(''Content-type: text/html; Charset=utf-8'');
echo "123";

and it works.

Regards

I had the same problem and found when I changed the response
ContentType header from "application/json" to
"text/javascript" IE7
could handle it.
