Pessoal tenho um um selectOneMenu, onde tenho apenas duas opções fixo e movel, quando o usuário seleciona movel aparece um outro selectOneMenu para escolher o ano, e quando ele escolhe fixo o selectOneMenu do ano some, quando vou salvar ele salva normal tanto fixo como movel, porém quando vou alterar um registro de movel para fixo o campo some, só que no banco de dados o selectOneMenu do ano teria que altera para nulo, porém ele continua com o ano cadastrado quando era movel, alguém sabe como faço para que quando eu for alterar e mudar de movel para fixo, altere para nulo no banco ?
Segue o Código
