Bean Validation: Composition request with failing parent entity hides additional errors from child entity

[mariodavid]

Given the following request:

POST {{baseUrl}}
         /entities
         /rstex11_Order?responseFetchPlan=order-with-details
Authorization: Bearer {{auth_token}}

{
  "customer": null,
  "date": "2021-03-01",
  "amount": 130.08,
  "lines": [
    {
      "product": null,
      "quantity": 2
    }
  ]
}

With "product": null in the child entity and customer: null in the parent entity, it only shows the error of the parent entity

[
  {
    "message": "may not be null",
    "messageTemplate": "{javax.validation.constraints.NotNull.message}",
    "path": "customer",
    "invalidValue": null
  }
]

Expected behavior:

[
  {
    "message": "may not be null",
    "messageTemplate": "{javax.validation.constraints.NotNull.message}",
    "path": "customer",
    "invalidValue": null
  },
  {
    "message": "may not be null",
    "messageTemplate": "{javax.validation.constraints.NotNull.message}",
    "path": "lines[0].product",
    "invalidValue": null
  }
]

so that the client can see all error of the complete entity graph at once.

Hi @mariodavid,

To achieve that just mark the list of lines as @Valid.
