If the URL given in dhtmlxAjax.getSync returns non-xml-data, for example a json-string,
I receive that string but the firefox error console shows the error
“not well formed” or “syntax error”.
How can I fix this?
Make sure that you are not using xml content-type.
Ok, I’ve put
Context.Response.ContentType = "text/html";
to the webservice-code and then there are no error messages.
