If you make any changes to an object and you don't commit these changes to the database, the following warning page will appear:
If you made a mistake and want to commit the changes, click Cancel. If you really want to lose your changes and transfer to the new page, click OK.
CAUTION:
This warning is not displayed if you are
working on a NEW object and you navigate to a different page.
Information about new objects is preserved in memory in
anticipation of your return to the page. For example, if you
are in the middle of adding a new user and you want to quickly
reference information on a different page, you will not receive
the above warning because your information will be saved. If
you use the back button to return to the user page, all of the
information you were adding will be present and you can enter
the rest of the new user's data.
