I followed Automatic Cataloging example in Zope Book, Chapter 9. Everything works fine except automatic cataloging of newly created fields ("author", "content"). When I change data in those fields it is not reflected in the catalog. When I add a new instance, it is not included in the catalog. This can be verified by clicking on the Catalog tab, and choosing the newly added instance (the page that says "the goal of this page is to provide basic debugging information about what is in the Catalog on a specific object."). Also, calling <dtml-in>Catalog</dtml-in> does not display new/modified data. The situation can be rectified by manually clicking Advanced/Update Catalog (for modified fields) or by Find Objects (for new instances). In other words, the catalog can only be updated manually. Strangely, the "date" field does not suffer this problem. I run Zope 2.3.1 source release. I use the latest Zope Book, dated March 13, 2001 Is the Zope Book text about Automatic Cataloging valid? What mistake I make? -- Milos Prudek
