You can use: request.isXHR() which checks against a header "X-Requested-With" set by the prototype library for AJAX calls. If you write your own AJAX stuff then request.isXHR() probably won't be set so you will have to set it yourself.

My app responds to Ajax event requests with JSON. If the event handler throws an exception, I'd like to return a special JSON response with the error text. Can I decorate RequestExceptionHandler for this? To do so, I'd need to be able to tell that the request is an Ajax event request; if it isn't, I'll delegate to the default RequestExceptionHandler. Is there a service I can use in my RequestExceptionHandler that'll tell me whether the request is an event request and not, say, a page request? -- View this message in context: http://n2.nabble.com/How-can-my-RequestExceptionHandler-distinguish-event-requests-from-page-requests--tp1635333p1635333.html Sent from the Tapestry Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
