[natfirst]

Environment

• Platform version: 7.2.10
• Forum issue https://www.cuba-platform.ru/discuss/t/kaskadnaya-validacziya-kolekczii/5233

Description of the bug or enhancement

1. Create a Customer entity
2. Create a Shop entity, create One to Many association attribute with Customer
3. Add annotations @Size(min=1) and @Valid as it described in documentation

@OneToMany(mappedBy = "shop")
    @Size(min = 1)
    @Valid
    private List<Customer> customers;

4. Create browser and editor screens for both entities, Shop editor screen should contain a table with Customers
5. Run the app and create Shop without customers

A.R. Nothing happens E.R. When an instance of Shop is validated, the list of customers will be checked for the fact that it contains at least one instance, and all instances of Product in the list will also be validated
