Instances of JCEvent are added to a ZCatalog but they are not automatically indexed by the catalog. The catalog is named 'events'. How can I automaticallly index them ? You are sure that you understand how indexing works?

There is a correspondence between the index names and attributes (maybe acquired, maybe parameterless method) of the index objects. Does a ZCatalog image match any of your ZClasses attributes? Dieter
