[TYPO3-commerce] Teaser text without RTE

[Rainer schleevoigt]

Hi,

in the editing area of products I want avoid RTE for short teaser text.

This is part of ext_tables.php:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
t3lib_div::loadTCA('tx_commerce_products');
$TCA['tx_commerce_products']['columns']['teaser']['config'] = 
Array('type' => 'text','rows' => 3,'cols' => 30);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It is unfortunately without effect. If I look in Configuration/TCA/ this 
change is visible in the tree.

By the way – 
$TCA['tx_commerce_products']['columns']['teaser']['config']['wizards'] = 
''; also doesnt work.
