Composant JSF personnalisé dans une page JSP formée de 3 select

Bonjour,

J'ai créé un composant jsf date de naissance dans ma page jsp, mais je n'arrive pas à récupérer les valeurs de mes 3 combos. Comment faut il faire ? A priori il n'accède pas à ma propriété valueChangeListener. Comment faut il faire ?
