[TYPO3] Localize to flags does not show up

[Bas van der Togt]

Hello list,

I'm working on a new multi-language extension.

When i take a look at all the records in the list view, none of my other 
languages are showing up below 'Localize to'.

This feature is working right with the normal content records.

Does anybody know what i'm missing, or doing wrong?

This is my ext_tables.php

$TCA["tx_myext"] = array (
	"ctrl" => array (
		'title'     => 'LLL:EXT:myext/locallang_db.xml:tx_myext_category',		
		'label'     => 'name',	
		'tstamp'    => 'tstamp',
		'crdate'    => 'crdate',
		'cruser_id' => 'cruser_id',
		'type' => 'sport',	
		'languageField'            => 'sys_language_uid',	
		'transOrigPointerField'    => 'l18n_parent',	
		'transOrigDiffSourceField' => 'l18n_diffsource',	
		'default_sortby' => "ORDER BY crdate",	
		'delete' => 'deleted',	
		'enablecolumns' => array (		
			'disabled' => 'hidden',
		),
		'dynamicConfigFile' => t3lib_extMgm::extPath($_EXTKEY).'tca.php',
		'iconfile'          => 
t3lib_extMgm::extRelPath($_EXTKEY).'icon_tx_myext_category.gif',
	),
	"feInterface" => array (
		"fe_admin_fieldList" => "hidden, name, sport, football",
	)
);

Thanks for your help!
Kind regards,
Bas
