I'm using the WebApiAdaptor to obtain my data from the server for the grid. I have that working perfectly. My question is how can I trap and display any errors returned from the API? I've tried using the GridEvents OnActionFailure, but the FailureEventArgs don't return any part of the error response from the API. Is there a specific response type that needs to be returned from the server on error from the API to be captured correctly by OnActionFailure and FailureEventArgs?
