When on the objectAdmin listing screen in FC7: If you have an object that has both “draft & approved” and then approve the object by checking the checkbox and clicking the approve button at the top of the objectAdmin screen, nothing appears to happen (it does record a log though saying that it was approved). The database entries appear to be untouched as well (for both draft and approved).
The checkbox and approve “do” work for new items that have not been approved yet.
