[RESOLVIDO] Problema ao fazer um CRUD no JSF

Front-end
#1

Olá pessoal!

Estou começando agora a desenvolver com java e estou tendo alguns problemas, pode ser até besteira mas como sou leigo ainda não consegui visualizar. Estou desenvolvendo uma aplicação usando JSF2 e spring IOC para injeção de dependencia e inversão de controle, nessa aplicação tennho o seguinte dominio:

Usuario, Grupo, Filial, Contrato, Boletim e ItemBoletim

O meu problema é na hora de adicionar os itens no meu ArrayList que se encontra no BoletetimMB, esta dando NullPointerException provavelmente deve ser alguma informação que esta faltando na criação do meu objeto em questão, mas já vefifiquei está duto certo.

Segue o código!

Minhas Entidades

@Entity
public class Boletim implements Serializable{
	
	/**

	private static final long serialVersionUID = 1L;

	@Id

na linha 98 da minha classe BoletimMB tem o seguint código:

boletim.getItens().add(item);

#5

acho que faltou inicializar sua lista, cara… ela deve estar nula.itens = new ArrayList<ItemBoletim>();

#6

Valeu amigo deu certo, muito obrigado pela sua ajuda, se não fosse você estaria quebrando a cabeça até agora valeu mesmo.

#7

Eu sei que parece difícil, mas tente aprender a ler a stacktrace, ela tem muitas informações valiosas.

Sei que ela pode ser intimidadora hehehe, mas tente.

Nela você consegue descobrir o erro, o causador do erro, e no seu caso, até a linha de código onde o erro foi causado.
Aí seria só colocar um breakpoint e tentar encontrar, caso você não tenha um teste pronto pra esse método.
