Problem to update data

Good morning friends, I am about 3 days with difficulties in an error that has been occurring in my application.

I have two entities, CUSTOMER and VEI. I did the mapping bidirectionally saying that my client may have one or more vehicles. 

private List<Veiculo> veiculo = new ArrayList<>();

@OneToMany(mappedBy = "cliente", cascade= CascadeType.ALL, fetch = FetchType.LAZY)
public List<Veiculo> getVeiculo() {
    return veiculo;}

I can make the registration of the Client and the vehicle related to him normally. However, I can’t edit them (atuzalizar). I created a screen where I search the client. Tela de pesquisa de cliente When I click the edit button, it takes the value of the id makes the conversation and I play the data already filled to the client edit screen. All values are filled in as they should normally, but when trying to save the client object after some change has been made. I have the following error.

    the quickest way to solve your problem would be to change your fetchtype to Eager, but depending on the amount of data you intend to have on your list this may get heavy, there are more specific ways but to quotelas would be interesting to understand more your code and your situation, here is some legal information: http://blog.caelum.com.br/enfrentando-a-lazyinitializationexception-no-hibernate/

  • Rodrigo, add in your post your save method. Change the fetch for EAGER probably would solve your problem, but at first it is not a good solution. By the way this annotation of LAZY nor is it necessary because by default lists are lazy.

  • Oops, Thanks friends, I tried to do as you explained to me. However when changing from fetch to eager the error reported is another. I will update the topic with the error in EAGER. And put the save method

  • Now the problem has completely changed context: interpolatedMessage='não pode ser nulo', propertyPath=placa. From the looks of it, you’re trying to save an invalid object.

  • Exactly, he asks me to report the value of the Vehicle related to the customer that I am trying to update. However how to do this if I do not want to update anything related to his vehicle, but only the customer data. ? I’m sorry I’m starting and I haven’t figured out how to solve.

  • He does not even check this variable, I do not know if it is relevant, more in my customer registration screen, I am adding my vehicle to the customer manually after the values are filled. start by instantiating a new vehicle, and a new client, and with the data already filled, I do so, public void register this.veiculo.setCliente(client); this.cliente.getVeiculo(). add(this.vehicle); } and then public void save() { registerCarro(); this.cadastroClienteService.save(this.client); Facesutil.addInforMessage("Register Saved successfully!"); }

    I believe you have identified what my problem is, I will try to execute the corrections and I warn you, thank you for your help. Excuse my lack of knowledge in perhaps providing you with little information, or distorted information. I return with news
