Hi all. I've been playing with creating custom Catalog Aware ZClasses for the last couple of days (following the various HowTos and tutorials), and I've run into a problem which has me stumped. I've been through all the documentation I could find, plus as many of the list archives I could deal with. Here's the situation: I created a new Product called "Library_Catalog". In that Product, I created a custom ZClass "LibCatClass" that is CatalogAware. I created a ZCatalog "library_catalog" and changed the Indexes and MetaData Table to include the following Class properties: Indexes (this is the complete list of custom class properties) book_comments (TextIndex) book_edition " book_isbn " book_catalog_date " book_publication_year " book_sub_genre " book_author " book_genre " book_publisher " book_title " book_description " MetaData Table book_sub_genre book_publication_year book_author book_isbn book_genre book_publisher book_title I also created a ZSearch Interface with "library_search" and "library_report" as the search/report DTML methods. I then modified the "LibCatClass_add" constructor to include the following: <!--#with "LibCatClass.createInObjectManager(REQUEST['id'], REQUEST)"--> <!--#call "propertysheets.LibCatItemInfo.manage_editProperties(REQUEST)"--> <!--#call "manage_editCataloger('library_catalog', REQUEST)"--> <!--#call index_object--> <!--#/with--> In the LibCatClass methods, I added "index_html", "edit_propertiesForm", and "edit_properties". The edit_properties method contains the following: <dtml-var standard_html_header> <!--#call "propertysheets.LibCatItemInfo.manage_editProperties(REQUEST)"--> <!--#call reindex_object--> <p>Changes saved.</p> <dtml-var standard_html_footer> (I'm not including the source of edit_propertiesForm because I'm fairly certain that it's irrelevant...if not, let me know and I'll provide it.) Up to this point everything works fine...I can add new instances and they're cataloged, I can edit the properties of those instances and the changes are automatically cataloged. All appears to be well. Having cleared the catalog and deleted all the instances, I made a few changes to the Indexes part of the catalog, which is when the problems started. I decided that I wanted to have a couple of "FieldIndex" type Indexes, so I deleted the book_genre index and recreated it with "FieldIndex" as its type. I can add new instances and they're cataloged okay, and I can edit the properties that are "TextIndex" types in the Indexes and everything is still okay. But, when I try to edit the book_genre property (that is the "FieldIndex" type) the instance no longer shows up when the catalog is searched. It's _in_ the catalog, but I get the "There was no data matching this library query" message when I search for it. So, I've been through the whole thing a dozen or so times, attempting to track down the bug. As far as I can tell, there is an issue related to reindexing an instance that includes a "FieldIndex" index type. Have I missed something obvious? Anyone have any idea how I can fix this? TIA - deb (yes, I'm basically a Zope newbie, but I'm sure having a lot of fun)
