Try accessing these parameters for your error part of the ajax call:

error: function (request, status, error) {
        alert(request.responseText);

Another example:

error: function(xhr) {
                if(xhr.status == 422) {
                  alert(parseErrors(xhr));
                } else {
                  alert('An error occurred while processing the request.');
                }

They are part of the ajax call you seperate them with a comma. So a little example:

$.ajax({
  success: function(data) {
  },
  error: function(xhr) {
  }
  });

Update: Basically xhr.status is the http status number.

alert("readyState: "+xhr.readyState);
alert("status: "+xhr.status);
alert("responseText: "+xhr.responseText);

when the error is thrown the value for xhr.status is 0 . Should it be something else if the error is valid ? – blue-sky Jun 18 '12 at 22:45

See the update section so you can see what else is in your returned messages for error, so we can see and put them in here. – Pasha Immortals Jun 18 '12 at 23:19
