isPartOfKey not being set correcting for keys in Embeddable properties

[jasonlfunk]

I have my keys stored in a UUID value object. When this is generating the metadata, the isPartOfKey flag is not being properly set for the classes.

Example:

/**
 * @Entity
 * @HasLifecycleCallbacks()
 **/
class Expense extends Base
{
    /**
     * @Embedded(class="Objects\UUID", columnPrefix=false)
     * @var UUID
     **/
    protected $id;
   ....
}

/**
 * @Embeddable
 */
class UUID
{
    /**
     * @Id
     * @Column(type="string")
     */
    private $id;

   ...
}

The generated Metadata looks like this:

{
"metadataVersion":"1.0.5",
"structuralTypes":[{
   "shortName":"Expense",
   "autoGeneratedKeyType":"None",
   "defaultResourceName":"Expenses",
   "dataProperties":[
      {"name":"id","dataType":"String"}
      ...
   ]
}

It appears that Embeddables aren't being evaluated correctly.

Embeddables is a Doctrine 2.5 feature. Yes it's not supported by the library yet. I'll have a look at the issue. Please feel free to contribute!

ok! Embeddables are the breeze equivalent of Complex Types.
Relating to your issue: The Doctrine documentation says embeddables don’t have a primary key which makes sense as they are not entities, but your UUID embeddable has a primary key like an entity. I think it is wrong. Second, your Expense entity has a primary key which is type of an embeddable. I wonder if Doctrine library supports Embeddable to be a primary key of en entity type.

Hi - thanks for responding.

1. You are right that an embeddable doesn't have a primary key because they aren't entities. However, they can provide the primary key for another entity. This setup is currently working fine with my application.

2. Expense doesn't have a primary key directly (there is no @id mapping on it). It get's inherited from the UUID embeddable.

Here are the relevant parts of the generated mapping:

I was hoping something would just ring a bell and there would be an easy fix. I don't have too much experience with Reflection and what-not. But I'll definitely dig into it a little more too.
