ContainsXxx field should be editable in UI #1860
Description
Example code
https://gist.github.com/abbadon1334/313e166efb598b8a416d6241c62ddbbb
if ContainsOne or ContainsMany fields in persistence are not null and an exception is raised :
Critical Error
Atk4\Data\ValidationException: ContainsXxx does not support unmanaged data modification
in Crud ContainsOne/ContainsMany must be not visible and should be managed by the framework when a model with those types of fields is added to crud
to solve some issues i already create these Helpers, but I like to have a way in the framework to avoid these helpers, any ideas?
