I have 4 models(Job,Parcel,Action, Spec) with following relation
<pre><code>
class Job
embeds_many :parcels
end
</code></pre>

<pre><code>
class Parcel
embedded_in :job
end
</code></pre>

<pre><code>
class Action
embed_one :spec
end
</code></pre>

<pre><code>
class Spec
embedded_in :car
end
</pre></code>

When i create first record everything is ok, but after creating second record, spec returns nil.

In the end, when i trying to save second record, mongoid updates first record spec instead of creating spec for new record.
