Description

used jquery.autocomplete which added $.ajax{dataType:"json"} which results in query adds jsonp callback and further the callback will cause a parse error, when removing the dataType spec. will cause correct behavior. In my scenario the response data structure is => [{"someproperty":"somevalue"}, {"someproperty":"somevalue"}]

Did a quick search for json in jquery-1.5.js and found this on row 6905:

// Detect, normalize options and install callbacks for jsonp requests
jQuery.ajaxPrefilter( "json jsonp", function( s, originalSettings, dataIsString /* internal */ ) {

removing the "json" from first argument will add correct behavior when spec. dataType:"json"

Are you using the jquery-validation plugin? It is not compatible with jQuery 1.5 and in particular causes the symptom you describe.

Yes, that is correct. I removed jquery-validation from loading and it makes things work. You can close this issue.

Thanks,

Daniel
