DataObjectAlreadyLockedException
This exception is triggered if it is attempted to set a lock for a data object and the lock already exists for that object or infringes another locking rule.
Locks for a data object are fundamental for changes to a data object in ChangeSets. A change, such as the renaming of a data object, will generate locks for this data object and any dependant data objects.
If for example a data object in a ChangeSet is moved into another level, then the data object to be moved is given the lock CsMoved and Existence. The lock Ordered locks this operation for other ChangeSets. The lock Existence locks all operations that would archive the data object. This means neither this data object nor the original superordinate data object can be deleted in another ChangeSet. Furthermore, the new superordinate data object is given the lock Existence. It is therefore ensured that this superordinate data object cannot be deleted and thus that the publication of the move could not lead to an error.
