This article explains how to add custom error handling in a K2.net 2003 Smartforms project. This can be illustrated by capturing the “All Worklist items have been allocated” exception.
| This error occurs when user ‘B’ selects a Worklist item, (which is still displayed as ‘Available’ in Workspace), after the item has already been allocated to user ‘A’. | ||
|
| ||
| Cause: User ‘B’s Worklist has not yet been refreshed.
| ||
| Resolution: Automatically refresh the Workspace of user ‘B’ whenever the error occurs, by doing the following: | ||
| 1. | Catch the error on the K2.net 2003 ASP.NET Smartform: | |
 | ||
| 1.1 | Select your client page’s properties | |
| 1.2 | Select the event properties for the page | |
| 1.3 | Specify an “Error” event | |
| 2. | The “Error” event will catch all errors that are raised when the page loads. | |
| 3. | Now you can receive each specific error message and specify a way to handle it | |
 | ||
| 4. | If the error message equals “All Worklist items have been allocated”, redirect to a new HTML (“Refresh.htm”) page you added to the project. | |
| 5. | On this “Refresh.htm” page, add a function to refresh the user’s Workspace. | |
