Originally created by @danitome24 on GitHub (Mar 27, 2017).

Hi,

I'm developing with DDD and doctrine and I would use embeddable for Value Objects. In my code, there are some Value Objects that I could reuse but due to a legacy code, these columns on database are different named. So I thought that I could update it on loadClassMetadata doctrine event. I also use Symfony.

To get this achievement I've started only assigning the embeddable to an entity from doctrine event like the following:

This code works and on dump I can see the embeddable Location object into embeddables array. The problem is when I fetch something and this Value Object (location) is null on my entity (Hotel).

Something wrong?

Versions:

Package	Vendor
Doctrine	2.5.4
Symfony	3.2.1

In general, what you would have to do is actually use the @AttributeOverrides annotation on you class using embeddable.attribute as name but due to the current limitation you can't really do it at the moment.

I think you're having this issue for the same reason we can't override embeddable objects.

How can I use @AttributeOverrides in YAML configuration? @lcobucci

@danitome24 1aa02f9afc/lib/Doctrine/ORM/Mapping/Driver/YamlDriver.php (L630)

But I recommend you to move away from YAML since it's already removed from the next major release.

@lcobucci Two last questions:

1. Why is YAML going to be removed? Performance?
2. When is going to be developed this feature? I'm waiting for it... if need help...

Thanks a lot 👍

Also, YAML it's a mess and we had tons of invalid issues because of syntax errors. You can see more on https://github.com/doctrine/doctrine2/pull/5932#issuecomment-233593524

2. When is going to be developed this feature? I'm waiting for it... if need help...

At the moment we're working on different things so it would be amazing if the community could send a PR to master that fixes that (maybe you?).
