[TYPO3-english] nested fe_groups in a tree view

at first i tried in the typo3conf/extTables.php (for me the normal place
- all other tables worked there):

$GLOBALS['TCA']['tx_news_domain_model_news']['columns']['fe_group']['config']['renderMode']
= 'tree';
$GLOBALS['TCA']['tx_news_domain_model_news']['columns']['fe_group']['config']['treeConfig']
= array(
  'parentField' => 'subgroup',
  'appearance' => array(
    'expandAll' => TRUE,
    'showHeader' => TRUE,
    'levelMaximum' => '10'
  ),
  'levelMaximum' => '10'
);

this crashes ext:news
(all news records have no title an couldn't be edited or created)

then i tried it at the end of localconf.php without any reaction
then i directly modified the TCA file for news in the extension and this
worked (but with my next problems when updating)


>> the tcaTree only shows 4 levels of fe_groups (in Database there are more
>> levels)
>> is this a restriction in the tree
>> (i tried to use 'levelMaximum' => 10, without success)
> 
> this is for sure a configuration
any hint where to find all configurations for treeConfig, i only find:
http://api.typo3.org/typo3v4/current/html/class_8t3lib__tree__tca__abstracttcatreedataprovider_8php_source.html
and so i tried "levelMaximum" but with no success...
