I created a new Display Item and set it's value to '?'. On the property sheet I added a Tooltip value, but the tooltip is not being displayed when I mouse over the display item. We are using forms 10.1.2.0.2. Any ideas?
I just tested this in Forms 11.1.2 and it works correctly. Likely what you are seeing is a defect and has been corrected. I would recommend that you install the latest and last full patch for 10.1.2, which is 10.1.2.3. Also keep in mind that version 10 is no longer supported. If you are using a licensed version of the product in a production environment, you should probably consider moving to a more current version.
