[Typo3] "CODE:" field in Extension

[Stefan Beylen]

ok, bernhard provided me the solution via ICQ

change the line
$TCA["tt_content"]["types"]["list"]["subtypes_excludelist"][$_EXTKEY."_pi1"]="layout,select_key";
to
$TCA["tt_content"]["types"]["list"]["subtypes_excludelist"][$_EXTKEY."_pi1"]="layout";
in ext_tables.php
and the code field will be shown after clearing the ext_ cache

it can be found via $this->cObj->data['select_key']

thanks bernhard!
