Multiple children arrays do not work at same nested level

[BrentH-Alnico]

Hi,

If I use the model below, the second array 'MenuItemTags' seems to overwrite the first array 'SizePrice' on the same level. I believe the model is correct or am I missing something?

$model = array(
    'key'=>'ItemTitle',
    'ItemTitle'=>'ItemTitle',
    'children'=>array(
        'SizePrice'=>array(
            'key'=>'MenuItemSize',
            'MenuItemSize'=>'MenuItemSize',
        )
    ),
    'children'=>array(
        'MenuItemTags'=>array(
            'key'=>'MenuItemTag',
                'MenuItemTag'=>'MenuItemTag'
        )
    )
);
