I have a ZClass (JBook) which is CatalogAware as its first class inheritance. When JBooks are added, they are added to the Catalog (default name, root level). However, if I request an update, the books are removed. Only the documents that were present when I did the last manual 'Find Objects' are kept. Can anyone shed any light on this?
