Probably your problem is that you're not using manage_addProduct. See 
the ZopeLabs recipe

However, check out

That'll give you a CMF-ized version, or help you CMF-ize ExternalFile if 
it doesn't do what you want.

FWIW, CMF-izing a product is basically

1) creating a new type, so that it is integrated into the CMF 
factory/types machinery, and
2) creating the skins to support adding, editing, and display
