Primefaces p:selectOneMenu não atribui valor selecionado à varável no bean

Front-end
#1

Olá pessoal,

Estou com esse problema a alguns dias e não estou conseguindo encontrar nenhuma solução. Já testei várias soluções aqui do fórum e de outros fórum e não tive sucesso.

Então resolvi criar um tópico pra ver se algum de vocês consegue me ajudar :\

O meu problema é que tenho um p:selectOneMenu que não salva a opção escolhida pelo usuário. A opção selecionada não está sendo armazenada no meu bean.

Muitas vezes quando executo o projeto, nem mesmo o valor key.name é atribuido corretamente. Acredito que o problema seja na submissão da requisição, mas infelizmente não estou conseguindo resolver.

Segue o código:
