Hi,

I have two objects, say:

class MyObjA extends DataObject {
  has_one = array('objB' => 'MyObjB');
}

class MyObjB extends DataObject {
  has_many = array('objsA' => 'MyObjA');
}

what I woul like to be able is when in CMS popup editing MyObjA, to have additional tab with loaded MyObjB with all it's data. I tried doing this in MyObjA:

function getCMSFields(){
  $f = parent::getCMSFields();
  $f->addFieldsToTab('Root.objB', $this->objB()->getCMSFields());
  return $f;
}

but all I get is bunch of empty fields. I also tried explicitly fetching related object by it's ID, but same result.
Is there a way to have in the same popup an object and it's has_one related object, so that I can edit them both (not edit the relation, but their data) at the same time?
