Fired when the Webroutine request fails
Member of DataRequest (PRIM_WEB.DataRequest)
|Reason||*Input||Enumeration||Reason code for the request failure|
|Handled||*Both||Boolean||Allow the error to be handled in the routine or forwarded to the application|
The Failed event is fired when the execution of a SrvRoutine fails. By default the runtime will end and an error message will appear in the browser. However, by monitoring for the event and setting the Handled parameter to True, the default error handling processing can be overridden and an application can be coded to better handle a failure. Failures not managed at this level can still be processed using the RequestFailed event.
|ServerError||An error occurred when executing the SrvRoutine. Check the joblog and x_err.log for further information|
|SessionInvalid||There is no valid session available on the server.|
|LicenseInvalid||The server license has expired|
In this example, when the request fails, some UI disabling code is called. The Handled parameter has not been set, so the error processing will continue. The error and can still be handled globally using RequestFailed, allowing the client application to continue.
