[Erp5-dev] processing relations when deleting an object

[Jean-Paul Smets]

Hi,

My advice is simple: do not delete the object. Instead, do something
else, such as moving it to a specific state such as cancelled, archived,
etc.

Other approaches (such as the one you describe) easily lead to data
destruction or inconsistencies, especially whenever security is involved.

I suspect the problem you encounter is more a problem of functional
analysis rather than a technical problem.

Regards,

JPS.
