[Erp5-dev] processing relations when deleting an object

[bartek]

Hello

Currently when an object to which some other objects are related is 
being deleted the system blocks the operation; however, there may be 
situtations when we'd like to do something else - like, edit relations 
so that the objects are no longer related, or delete all the related 
objects in a 'cascading' way.

I need something like this now, so the question is, what would be a 
clean way to implement such a feature? Perhaps it could be a kind of a 
configurable interaction, but which would be executed before 
Object_hasRelation does its checks (I experimented with interaction 
workflow, but if there are related objects that stage is not even reached).

What would you advise?
