相关实体的瓦丁积垢用户界面

vaadin orm view user-interface java

如何显示相关实体的UI部件?

如果我有这样的产品实体网格

    GridCrud<T> crud = new GridCrud<T>(tClass);
    crud.getCrudFormFactory().setUseBeanValidation(true);
    crud.setFindAllOperation(() -> (Collection<T>)repository.findAll());
    crud.setAddOperation(repository::save);
    crud.setUpdateOperation(repository::save);
    crud.setDeleteOperation(repository::delete);

接下来是产品

public class Product {//...
@ManyToMany
@JoinTable(name = "optionToProduct",
        joinColumns = {@JoinColumn(name = "optionId")},
        inverseJoinColumns = {@JoinColumn(name = "productId")})
private Set<Option> options = new HashSet<>();
}

如何在编辑期间显示每个产品的选项列表?
