Resolvido Hibernate save mas não update

Front-end
#1

Estou com um problema realmente estranho, consigo salvar um objeto no banco sem problemas, já quando é pra dar um update o hibernate lança nullpointerexception. Alguém sabe me dizer com resolver esse problema?

Não sei se tem a ver, mas esse objeto que estou tentando dar o update é relacionado com outras 3 classes. Estão mapeadas da seguinte forma:

Tabela usuário:

	@OneToMany(targetEntity=TbContato.class, mappedBy="usuario", fetch=FetchType.LAZY, orphanRemoval=true)
	@Cascade({org.hibernate.annotations.CascadeType.ALL})
	private List<TbContato> contatos;
	
	@Cascade({org.hibernate.annotations.CascadeType.ALL})
	@OneToMany(targetEntity=TbUsuarioLog.class, mappedBy="usuario", fetch=FetchType.LAZY, orphanRemoval=true)	
	private List<TbUsuarioLog> usuarioLogs;
	
	@OneToOne(mappedBy="usuario", targetEntity=TbAtividade.class, orphanRemoval=true)
	@Cascade({org.hibernate.annotations.CascadeType.ALL})
	private TbAtividade atividade;

E as classes da outra “ponta”:

	@OneToOne(fetch=FetchType.LAZY)
	public TbUsuario usuario;

	@ManyToOne()
	public TbUsuario usuario;	

	@ManyToOne
	public TbUsuario usuario;

Segue o stack trace:

Ele não está null, estranho demais esse erro cara. Quando salvo vai de boa, já no update da esse erro =/

#4

Já tentou debugar para ver onde exatamente ocorre o NullPointException?

Roda o método passo a passo, para ver onde está sendo chamado algum método em objeto nulo.

Confira o código que lança erro abaixo.

Problema resolvido!
Depois de muitas alterações googladas e tentativas, consegui finalmente resolver esse problema. Mas foram tantas alterações que nem sei o que realmente corrigiu o bug rs. Obrigado!
