[Pharo-project] Registering a tool in the world menu

Hi list, I'm using PharoCore 1.1 #11301. Now I want to adapt some tools to use the new menu registration mechanism. When I evaluate: menuCommandOn: aBuilder <worldMenu> (aBuilder item: #'Dependency Browser') parent: #Tools; action:[self open]; icon: UITheme current windowMenuForm. the world menu is modified including only the Dependency Browser item and all remaining items were removed. Did I miss something? Cheers, Hernán
