Hi,
I have the following structure:

class SomePage extends Page {
	static $has_one => array(
		'SomeImages'	=> 'SomeImage'
	);
	static $has_many => array(
		'SomeDataObjects'	=> 'SomeDataObject'
	);
}
...
class SomeDataObject extends DataObject {
	static $has_one => array(
		'SomePages'	=> 'SomePage',
		'SomeImages'	=> 'SomeImage'
	);
}
class SomeImage extends DataObjectDecorator {
	function extraStatics() {
		return array(
			'db' => array(
				'Copyright'	=> 'Varchar(50)'
			)
		);
	}
}

Since copyrights directly belong to one specific image, and since they should be set ideally together with uploading an image (either related to SomePage or SomeDataObject, that shouldn't matter), I would like to create a TextField in SomePage and SomeDataObject that writes and gets it's values directly to and from the Copyright db-field in SomeImage.

My question: is this possible and how...?
