[TYPO3-dev] Changing page title from plugin

[Philipp]

Hey, i think its real basic stuff but i just cant do it.... How do i set meta tags from my action?

none of the following does the job....

$GLOBALS= 'FOO';
$GLOBALS['TSFE']->indexedDocTitle = 'FOO';
$GLOBALS['TSFE']->indexedPageTitle = 'FOO';
$GLOBALS['TSFE']->getPageRenderer()->setTitle('title test 12');
$GLOBALS['TSFE']->getPageRenderer()->addMetaTag('<meta name="author" content"TEST" />');

TYPO3 Version is 6.0.3
