[Erp5-dev] how to really hide some allowed portal types

[Mikolaj Antoszkiewicz]

Hello,

Is there a way of modifying the stock Allowed Portal Types list without 
using Hidden Portal Types and modifying stock BusinessTemplate?

Or the other way, is there a 'proper' way of stopping 'New' icon on the 
module form (Folder_create()) from creating random object from Allowed 
Portal Types list, even though it is hidden?

Regards
