Any time a cartridge handler has a name that does not match its cartridge type exactly, it must be registered in the /atg/endeca/assembler/NucleusAssemblerFactory.handlerMapping property. For example, The CategoryHeaderBanner component is registered in the NucleusAssemblerFactory.handlerMapping property as the handler for cartridges with an ID of HeaderBanner-ATGCategory. The following mappings for cartridge type and handler are defined in Commerce Reference Store:

  ContentSlot-Header=/atg/endeca/assembler/cartridge/handler/ContentSlot,\

Note: The PriceSlider cartridge handler has the same name as the PriceSlider cartridge, so it does not need to be registered in the handlerMapping property.
