@dbu I couldn't get the autoname to work in the uow of phpcr-odm:
- this method says that the namehint is invalid: ``$node = $parentNode->addNodeAutoNamed(PathHelper::getNodeName($id), $class->nodeType);``;
- and once a node with the same name already exists an exception is thrown before the code reaches ``executeInserts`` were the autonaming should do it's work

The solution now used is the same workaround as used in the block bundle for slideshows, it is anyhow better then what we had before in create.
