tente colocar o id da datatable no update do botão atualizar…

#3

Coloca o teu actionListener que está no botão que chama o dialog, no botão OK que está no seu dialog

Troca sua action pra cá:

[quote]<p:commandButton value="OK"
type=“submit” ajax=“false"
update=”:principal"
style=“margin-left: 45px;width: 80px”/> [/quote]
