Testing

To see how timestamping will prevent lost update problems, do the following:

  1. Run the sample application.

  2. Launch up two instances of your favorite Web browser.

  3. In browser one, search and display the detail form for a Publisher record.

  4. In browser two, search and display the detail form for the same Publisher record shown in browser one.

  5. In browser two, make a change to the Publisher's data, click the Update button, and wait for the confirmation message to display.

  6. Switch back to browser one, make a change to the Publisher's data, and click the Update button. If everything works as planned, you should receive an error message stating the update could not be completed because the Publisher was updated by another user.
