I decided to convert my ZClasses to CatalogAware. I added CatalogAware as first base class. If I add <dtml-call "index_object()"> in my MyZClass_add method, then new object is automatically indexed as expected. But in CatalogAwareness.py I see method manage_afterAdd, which does the same. Is this method called automatically (probably not), or have I to call it - where, what arguments ? I tried to call it after call to _add method - I got strange error: Error Type: AttributeError Error Value: _u This ZClass base classes are CatalogAware and DTMLDocument. Without mentioned call to "index_object", object is not indexed. I need some enlightenment on manage_afterAdd - how (and why) to use it, and CatalogAware in general :) Of course, I can put "index_object()" in every _add method, but probably it's not the right way of doing things. ololo@zeus.polsl.gliwice.pl /--------------------------------------\ | `long long long' is too long for GCC | \--------------------------------------/
