UBAQ with a tracker, after search, no changes made close form asks to confirm save

Hello all,

We are on 10.2.300.11.
I have created a pretty vanilla updatable dashboard to update a UD field in partrev table. I have a tracker with a textbox bound to search PartNum starts with.

User enters text, press Refresh button, only one line appears with the correct PartRev row.

Issue: If user does nothing after the refresh and closes the form, the message to confirm a save shows up. But all the user did was to perform a search, and decided not to update the field, and closed the form. So no changes were made into the updatable field.

Is this a bug? Or is there a setting I missed during creation?

Thanks

Pierre
