Duvidas com collection

Olah pessoa!
minha duvida eh a seguinte...
tenho uma aplicacao web q gera varios relatorios utilizando collections mas oq ocorre eh q somente eh exibido um regitro por vez!!
pra q a aplicacao "enchergue" os novos registros inseridos ou excluidos tenho q reiniciar o servidor!
isso jah aconteceu com alguem?!
alguem sabe como posso contornar isso?!
obrigado!

Olá.

Verifique se os commits estão ocorrendo certo.

Posta o código da sua classe que popula as collections aqui no fórum, ai fica mais fácil dizer o que pode ser.
