[TYPO3-mvc] Problems using 1..N relationships within STI

[Hauke Stange]

Ok, just found the flaw myself.

I configured the 1:N relationship in the TCA via 'select' but it has to
be 'inline'. Makes more sense obviously because this gives me the
ability to declare the coresponding property / field by the
'foreign_field' setting.

'bar_objects' => array(
    'label' => 'Liste mit Bar-Objekten',
    'config' => array(
        'type' => 'inline',
        'foreign_table' => 'tx_gpqg_domain_model_basisklasse',
        'foreign_field' => 'foo_reference',
        'foreign_table_where' => 'AND
`tx_gpqg_domain_model_basisklasse`.`record_type` =
\'Tx_Gpqg_Domain_Model_UnterklasseBar\'',
        'maxitems' => 999
    )
),
