Bonjour

je veux remplir un datagrid et un pie chart en flex à partir d'un service java avec une liste de nombres de tickets pour chaque type de status suite à un clic sur un boutton , mon problème est que j'ai parvenu à récupérer chaque nombre à part et lorsque je l'affiche dans des labels c'est correct mais lorsque je mes tous ces nombres dans une liste coté flex pour que je puisse remplir un datagrid ne varient pas lors du clic sur le boutton ,la datagrid reste remplie avec des 0 (ce sont les valeurs initiales)je reste bloqueé car j'ai pas su comment je dois faire un refresh au datagrid vous trouverez ci joint un genre de truc que je veux obtenir(datagrid rempli par de stattistique) et ce que j'ai obtenu avec mon travail (juste des labels séparés et si j'essaie de remplir un datagrid il reste remplie par des 0)
voilà mon code flex
