[TYPO3-german] Extbase und Flexforms

[Hendrik]

Hi,

ich weiß leider nicht was ich hier falsch mache... Das Flexform
erscheint im BE einfach nicht.

was mache ich falsch?
danke schon mal...




ext_tables.php:
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::registerPlugin(
	$_EXTKEY,
	'Singleitem',
	'NN Single Item'
);

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addStaticFile($_EXTKEY,
'Configuration/TypoScript', 'NN');

// Include flex forms
$extensionName =
strtolower(\TYPO3\CMS\Core\Utility\GeneralUtility::underscoredToUpperCamelCase($_EXTKEY));

$pluginName='Singleitem';
$pluginSignature = $extensionName.'_'.$pluginName;
$TCA['tt_content']['types']['list']['subtypes_addlist'][$pluginSignature] =
'pi_flexform';
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPiFlexFormValue($pluginSignature,
'FILE:EXT:'.$_EXTKEY . '/Configuration/FlexForms/Singleitem.xml');





das flexform:
