[CreateMultiLingualMap] Id of the entity is replaced by the id of the translation in the mapping

Problem (using the documentation example)

While using the new (awesome and much anticipated btw) Multi Lingual Entities feature, i needed to get the id of the product with the translated name in the ProductListDto class.

public class ProductListDto: EntityDto
{
    // Mapped from Product.Price
    public decimal Price { get; set; }

    // Mapped from ProductTranslation.Name
    public string Name { get; set; }
}

I’m getting the correct translation for name but the Id (from EntityDto) is getting the ProductTranslation Id not the Product one (using CoreId as a property does the Job of getting the correct one instead)

Suggestion

If i understand correctly, in the CreateMultiLingualMap extention, in the aftermap, we check if there is a Translation so we map it and at the same time it replace the id.

@valleen I think I have found the issue but this is an EF Core problem. When you clear the Translations while you are updating your entity, it is not removed from database and probably still exist in the change tracking. So, if you change your update method like this, it will work.

public override async Task<CategoryDto> Update(CategoryDto input)
{
	CheckUpdatePermission();

	var category = await _categoryRepository
		.GetAllIncluding(c => c.Translations)
		.FirstOrDefaultAsync(c => c.Id == input.Id);

	category.Translations.Clear();

	await UnitOfWorkManager.Current.SaveChangesAsync();

	ObjectMapper.Map(input, category);

	await _categoryManager.UpdateAsync(category);

	return await Get(input);
}

@valleen sure.
