Symfony CMF StaticContent show all child blocks in PHPCTRee?

问题

Does anybody know how I can make all child blocks show up on the CMF Tree in the Sonata Admin for the StaticContent class?

The way our system uses the Symfony\Cmf\Bundle\ContentBundle\Doctrine\Phpcr\StaticContent class is to just use it as a content document that we can attach other blocks to. I thought that was the purpose of the ContentBundle. Instead only blocks inside of this additionalInfoBlock container block appear in the tree. Unless I am doing something wrong. I have looked at

Symfony/Cmf/Bundle/ContentBundle/Resources/config/doctrine-model/StaticContent.phpcr.xml:

<child name="additionalInfoBlock">
   <cascade><cascade-persist /></cascade>
</child>

There has to be way to get all the child blocks show. I just dont want to start hacking the PHPCRTree class to do this. Do I extend StaticContent and hopefully it will show all children? How do I go about this if that is the answer. Or is there another setting.

See this image below of what I can see in jackrabbitexplorer vs what is in the CMF Tree in the Sonata admin
