Thanks, All the products have meta_types, but I did not declare them in the __init__.py file because I dont want them visible in standard zope folders. I specified them explicitly in the all_meta_types of the container. But that is not the problem becaues I have 4 products all, almost identical and two will copy/paste and two will not. some methods are different, but I cant work out what affects the ability to copy/paste.
