During an optimistic batch update, a collision may occur where a second client modifies the same field and record in between the time the first client retrieves the data and the first client's update attempt. The
OriginalValue property contains the value of the field at the time the last batch
Update began. If this value does not match the value actually in the database when the batch
Update attempts to write to the database, a collision occurs. When this happens, the new value in the database will be accessible through
the
VisibleValue property.
