Complex fields / structs not working as documented (Golang Example)

Description

The documentation example under “Complex fields / structs” (https://golang.objectbox.io/entity-annotations#complex-fields-structs) doesn’t work as shown. When embedding inline structs without their own ID field, the ObjectBox code generation fails, complaining that the inline struct has “no property recognized as an ID”. It seems every embedded struct also needs an ID.

Basic info

• ObjectBox version v1.9.0 (go) and v4.0.0 (generator)
• Reproducibility: always
• Device: Desktop
• OS: Debian Bookworm
• Runtime: mcr.microsoft.com/devcontainers/go:1.24-bookworm

How to reproduce

Steps to reproduce the behavior:

1. Create a Go struct that embeds another struct without its own ID, e.g.:

   package model
   
   //go:generate go run github.com/objectbox/objectbox-go/cmd/objectbox-gogen
   
   type Metadata struct {
       Name string
       Info string
   }
   
   type Task struct {
       ID       uint64 `objectbox:"id"`
       Title    string
       Metadata Metadata
   }
   
   

2. Execute go generate ./...

Thanks for reporting! We'll try to verify this once there is time.
