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

fun)
