Explicit FK mapping syntax for HAS_ONE not supported

[a9rolf-nb]

To quote from the Yii AR documentation:

In case you need to specify custom PK->FK association you can define it as array('fk'=>'pk'). For composite keys it will be array('fk_c1'=>'pk_с1','fk_c2'=>'pk_c2').
(docblock in source)

Not talking about the composite key case here. Simply using the same syntax to explicitly name single foreign column => single local column.

If you have an AR child class with this:

// model's own primary key is (`nodeId`)

public function relations()
{
    return array(
        'parentRelationRecord' => array(
            self::HAS_ONE,
            'ProjectNodeParent',
            array('nodeId' => 'nodeId'),   // trivial case
        ),
        'status' => array(
            self::HAS_ONE,
            'Status',
            array('id' => 'statusId'),
        ),
    );
}

... saving triggers a PHP warning in EActiveRecordbehavior::afterSave Line #233

229    // update all not anymore related records
230    $criteria=new ECompositeDbCriteria();
231    $criteria->addNotInCondition(CActiveRecord::model($relation[1])->tableSchema->primaryKey, $newPKs);
232    // @todo add support for composite primary keys
233    $criteria->addColumnCondition(array($relation[2]=>$this->owner->getPrimaryKey()));

At this point, PHP is trying to use an array as an array key, which it can't. This causes the warning.
This call is initiated from CActiveRecord::afterSave and the event it triggers.
