> Key: TAP5-1941
> URL: https://issues.apache.org/jira/browse/TAP5-1941
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-core
> Affects Versions: 5.3.3
> Reporter: Felix Gonschorek
> Assignee: Howard M. Lewis Ship
> Priority: Minor
> Fix For: 5.4
>
>
> The Alerts component does not check for request.isXHR() in the "onDismiss" event handler.
> Crawlers (Googlebot) send non-xhr requests to the "onDismiss" event-url and generate errors on my server, because the returned JSONObject is not a valid return value from an event handler.
> org.apache.tapestry5.runtime.ComponentEventException: A component event handler method returned the value {}. Return type org.apache.tapestry5.json.JSONObject can not be handled.
> A check for request.isXHR() and a conditional return value (null for non-ajax requests, the json object for ajax requests) should fix this.
> thanks!
