Originally created by @yceruto on GitHub (Feb 11, 2016).

Originally assigned to: @Majkl578 on GitHub.

I've an entity with one embedded field:

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Table(name="box")
 * @ORM\Entity()
 */
class Box
{
    //...

    /**
     * @var Payment
     *
     * @ORM\Embedded(class="AppBundle\Entity\Payment")
     */
    private $payment;

    //...
}

Running the command: doctrine:generate:entities AppBundle:Box -vvv throws an exception:

I've changed this lines and work for me (source):

- $this->reflClass->name,
- $embeddable->reflClass->name,
+ $this->name,
+ $embeddable->name,

if they agree I can create a PR to fix this.

@Ocramius commented on GitHub (Feb 11, 2016):

The change seems wrong to me: an entity name is not necessarily its reflection class name in all cases. Wondering why the reflection wasn't initialized in that case, but it seems like the doctrine bundle is using a "cold" reflection service.

Exactly, in this case the reflection service class is StaticReflectionService, then $this->reflClass is null. What would be the right solution?

Wondering if populating the reflection with a fake reflection instance could work. This reflection service has bitten us many many times...

@Ocramius I've another issue related with the same command doctrine:generate:entities
when exists more than one levels embedded, I found this commit with a solution but I don't see it in 2.5 or master branchs.

The exception is thrown here, because here $parentReflFields it's empty on first occurrence, I don't see the solucion in your tree reference ??

I had the same error and found solution. If I provide only class name:

/**
 * @var Price
 *
 * @ORM\Embedded(class="Price")
 */
private $price;

I get this error when running doctrine:generate:entities. However when I add columnPrefix:

/**
 * @var Price
 *
 * @ORM\Embedded(class="Price", columnPrefix="price")
 */
private $price;

then it works. :)

@Adam314 adding columnPrefix seems to work for one level of embeddable but not multiple.

I had to change https://github.com/doctrine/doctrine2/blob/v2.5.5/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php#L930
to

if (isset($embeddedClass['declaredField']) && $parentReflFields[$embeddedClass['declaredField']]) {

to get this working.

Same issue here but adding columnPrefix does not solve the problem for my case:

class CreditNote
{
    /**
     * @var BillingRecipient
     *
     * @ORM\Embedded(class="AppBundle\Embeddable\BillingRecipient", columnPrefix="recipient")
     */
    private $recipient;
}

Removing the embedded field makes the command work.

Lovely workaround @Adam314 the solution (including the columnPrefix) works in 3.2 for one level of embedding
