It's based on ZObject and ZClass_for_Catalog_Aware. ZClass_for_Catalog_Aware was the first base class when it was created.
Now this sort of works... this dtml snippet will display just "news:" when a new instance of the News Item zclass is added to the site, meaning that it KNOWS there's a new instance of News Item.... for each news item that gets added, it will display another instance of the text "news:". So on my front page, if I have five news items zclass instances in my site, it'll look something like this:
However, it wont display any of the dynamic content eg. <!--#var department-->, <!--#var subject-->, etc. until I go into the Catalog Zcatalog and manually update the catalog. Once I manually update the zcatalog, I get content like:
AppDev news: This is news.
[lots of snipping above] A CatalogAware ZClass will automatically add and remove itself from the catalog. However, it does not update the catalog when properties are changed. This includes in the ZClass_add method... You need to: 1) add the line "<dtml-call reindex_object>" after you call "propertysheets.properties.manage_changeProperties..." 2) If you want to be able to edit these, create a form that essentially duplicates the propertysheet form and post the results to a dtml method like this: <html><body> <dtml-call "propertysheets.properties.manage_changeProperties(REQUEST)"> <dtml-call reindex_object> <p>Changes saved.</p> </body></html> Kevin
