InvalidObjectException

Description:
The exception that is thrown when referencing an object that is no longer valid.

Remarks:
The object may no longer exist for many reasons:

The object was explicitly deleted from the database.
A change to other database items caused the item to be automatically deleted from the database.
The object no longer exists as its creation was undone (by rolling a transaction back).
