If the JSON string is not correct it will throw an browser error. Try
to catch all errors with an global error handler:
<script type="text/javascript">
function OnError(e) {
alert(AjaxPro.toJSON(e));
}
addEvent(window, "error", OnError);
</script>
Why does the customer not help you with this stuff? And maybe you can
add a proxy on the web server to see what is transfered to and from
the client.
