Web Application - RequestFailed Event
Fired whenever a request to a server routine fails
Member of Web Application (PRIM_WEB.Application)
| Name | Type | Data Type | Description |
|---|---|---|---|
| Request | *Input | PRIM_WEB.ServerRequest | Reference to the request that failed |
| 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 RequestFailed 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. Individual request failures can also be detected using the Request Failed event.
| Enum Value | Description |
|---|---|
| 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 event fired, the Handled is set to true and the applcation reports the error. Despite the server failure, the client application will continue to execute.
