Siebel Business Process Framework: Task UI Guide > Creating Steps and Connectors > Creating an Error StepAn error step is a type of task UI step that creates an error message and returns control to the current view. It allows you to configure Siebel CRM to display an error message in the Siebel client. This functionality is typically required if an error message that a business service returns is not sufficiently clear to the user. The error step in a task UI supports an exception in a way that is similar to how the Stop step works in a workflow process. For example, assume a business service step in a task UI calls an external system, the external system is down, and an error occurs. An exception branch and an error step handle this error. If the error step runs, then Siebel CRM does the following work:
You can use an error step in an exception branch or as part of the normal logic of a task UI to handle an expected error.
How Siebel CRM Handles an Error While a Task UI RunsIf an exception occurs in a task step while the task UI runs, and if no exception branch is defined, then Siebel CRM displays a generic error message in a dialog box that it displays on top of the current task view. The user can acknowledge the error message, and then correct the data in the task view, or can navigate to a previous task view to correct the data. This configuration is known as default exception handling. How Siebel CRM Handles an Error When the User Pauses a Task UINo exception handling occurs if a user pauses a task UI. If a paused task fails, then Siebel CRM displays a typical error message, not a pause error. The user can cancel or continue the task. How Siebel CRM Handles an Error When the User Cancels a Task UIIf the user clicks Cancel, then Siebel CRM displays a dialog box that prompts the user for confirmation. For example, if the user is about to perform a delete or undo operation in a task UI, and then clicks OK to continue. |
