[TYPO3-mvc] object properties as Tx_Extbase_Persistence_ObjectStorage but without tca

[Simon Schaufelberger]

Hi extbase people,
I have a problem with my domain model at the moment.
What I have is a project model with some properties that are stored in 
the db like name and so on. All these properties are defined in the TCA.

Now i want to add an additional property $subprojects like that:

/**
  * subprojects
  * @var 
Tx_Extbase_Persistence_ObjectStorage<Tx_PtExtlistTimesheet_Domain_Model_Project>
  * @lazy
  */
protected $subprojects;

i also have a constructor for that:

public function __construct() {
	$this->subprojects = new Tx_Extbase_Persistence_ObjectStorage();
}

I don't call the constructor directly but instead i do the following in 
my controller:

$project = $this->projectRepository->findByUid(123);
print_r($project);

and what is get is:
----snip----
[subprojects] =>
----snip----

to make this work, i HAVE TO configure subprojects in the TCA which i 
DON'T want since i don't want to store the subprojects in the DB.

what i expect is:
----snip----
[subprojects:protected] => Tx_Extbase_Persistence_ObjectStorage Object
         (
             [storage:protected] => Array
                 (
                 )

             [isModified:protected] =>
         )
----snip----
this can be done with a little hack like insert this line after getting 
the project from the repository:
$project->setSubprojects(new Tx_Extbase_Persistence_ObjectStorage());
but imho this is ugly.

Later i will call a function in the model to fill the subprojects from a 
repository like $project->getSubprojects(); and then do some magic in 
there ;)

I think this needs to be fixed in extbase so that object storage 
properties can also be used without any tca configuration.

What do you think?
