steps to reproduce
1. login to test, open bpartner info window
2. on the bottom toolbar select create record
3. fill name, try to save, stop you fill address. result: PASS
4. leave empty name field, save-ok it. result FALL - as result allow close Quick Entry by OK button.
Awaited behaviour: validate field mandatory settings.

I think that scenario is somewhat correct, same if you open the quick entry window and push OK without filling any value, the system interprets -> nothing changed here, OK to save without validating or saving anything.
