[PrimeFaces / datatable] Pagination ne marche pas
Bonjour a tous
je développe une application qui manipule un énorme volume de donnée. Mon environnement de développement est : spring 3+hibernate 4+jsf2+primefaces.
Pour pouvoir gérer les données j'ai choisi la "lazyloading dataTable" de primefaces.
Sauf que lors de l'execution, ca m'affiche uniquement les 10 premieres lignes de la BD. et si je veux passer a la page suivante ca marche pas.
