Primefaces 3.2 - datatable bug ?

C'est une impression ou ce composant est bourré de bugs :furieux:

je fais des tests avec la version 3.2 de primefaces et j'ai des comportements complètement aberrants.

j'affiche une première fois la page, je peux utiliser le paginator, mais les liens ou les boutons ne fonctionnent plus après.

ou alors j'affiche une première fois la page, je fais une opération sur la liste, et il n'y a plus que les indexes qui changent, la liste ne bouge pas ou alors je me choppe des erreurs NumberFormatException

Mais d'où ça vient ?
