AbsoluteItemIdList returns a pointer to a fully qualified ItemIdList of the current object.
property AbsoluteItemIdList: IItemIdList;
This property should only be used by advanced users. It sets or returns the absolute ItemIdList of the current object. The returned pointer to an ItemIdList will be valid, until a new object was selected. So if you want to store the returned ItemIdList for using it again later, you have to copy it using IItemIdList.
