XAJAX Error: The XML reponse that was returned from the server is invalid

Mostly it's a problem with character encoding of the XML and the way IE interprets it. It seems that IE hates any character that is illegal for that encoding, so for instance special chars like Umlaute or a cedile is not taken kindly iif the character set is not put right in the XML header.

in Xajax that's the job of the xajaxResponse

so - in order to set this straight, in a joomla environment , just add below every

 

$objResponse = new xajaxResponse();
 
 
the following lines
 
$iso = split( '=', _ISO );
$objResponse->setCharEncoding($iso[1]);
 
 
That should take care of it.
