[Zope-dev] define restricted list of meta types for subobjects

[zope-mailinglist]

hi

i made a folderish product which inherits from objectmanager

to define which meta_types the user should be able to put into it i have 
overriden
"all_meta_types" from objectmanager

now only those returned from this function are displayed in the product 
add list in the ZMI
but i can still add other subobjects when i play with the url and call 
the addform directly.

my q:
is there a method to define this subobjects via permissions without 
setting permissions each time a product class is instanciated
i read about some "permission key" for a specific meta type. but i want 
to set the permissions only for a specific product, independend of the 
instances location

thx in advance,  bernd
