I’ve had this happen before with Spring @ResponseBody and it was because there was no accept header sent with the request. Accept header can be a pain to set with jQuery, but this worked for me source $.postJSON = function(url, data, callback) { return jQuery.ajax({ headers: { ‘Accept’: ‘application/json’, ‘Content-Type’: ‘application/json’ }, ‘type’: ‘POST’, ‘url’: … Read more
success has been the traditional name of the success callback in jQuery, defined as an option in the ajax call.

Indeed, UIComponent#findComponent() as done by <f:ajax render> fails when using <h:form prependId=”false”>. This problem is known and is a “Won’t fix”: JSF spec issue 573. In my humble opinion, they should never have added the prependId attribute to the UIForm during the JSF 1.2 ages. It was merely done to keep j_security_check users happy who … Read more
