I tried but that didn't work. I must put

     // Call all addGlobalMarkers hooks at the end of this method
		if (is_array 
($TYPO3_CONF_VARS['EXTCONF'][TT_PRODUCTS_EXTkey]['addGlobalMarkers'])) {
		    foreach 
($TYPO3_CONF_VARS['EXTCONF'][TT_PRODUCTS_EXTkey]['addGlobalMarkers'] as 
$classRef) {
			$hookObj= &t3lib_div::getUserObj($classRef);
			if (method_exists($hookObj, 'addGlobalMarkers')) {
			    $markerArray = 
array_merge($hookObj->addGlobalMarkers($markerArray),$markerArray);
			}
		    }
		}
