I'm having the following problem I have three tables one with the name

User with the following properties Id, User, UserName and Password

Person with the following Id, Name

Employee with the following properties Id, Job, User_ID, and Person_ID

I use the user to login to the system.

When I am going to register the employee I need to pass to the employee table the id of the logged in user that is already saved in the database.

I'm getting the following error?

object references an unsaved transient instance - save the transient instance before flushing

I'm having to save according to the code below:

    public void salvar() {
    FacesContext context = FacesContext.getCurrentInstance();
    try {

        //Salvar Insert Id do Objeto Usuário para a Tabela Funcionario Id_Usuario.
        this.funcionarioModel.setUsuarioModel(usuarioModel);  

        //Salvar Insert Dados de Pessoa da Tabela Pessoa e o Id do Objeto Pessoa para Tabela Funcionario Id_Pessoa
        pessoaModel = this.pessoaController.salvar(this.pessoaModel);
        this.funcionarioModel.setPessoaModel(pessoaModel);
        this.pessoaModel = new PessoaModel();

        //Salvar Insert Dados Tabela Funcionario 
        this.funcionarioController.salvar(this.funcionarioModel);
        this.funcionarioModel = new FuncionarioModel();

        context.addMessage(null, new FacesMessage("Funcionario salvo com sucesso!"));
    } catch (NegocioException e) {
        FacesMessage mensagem = new FacesMessage(e.getMessage());
        mensagem.setSeverity(FacesMessage.SEVERITY_ERROR);
        context.addMessage(null, mensagem);
    }
}

Edit

Hi Felipe, just one more question if you can help me, followed the reasoning that you understood well. I have the UserRepository class as below;

package br.com.repository;

import java.io.Serializable;
import java.util.List;

import javax.inject.Inject;
import javax.persistence.EntityManager;
import javax.persistence.TypedQuery;

import br.com.model.UsuarioModel;

public class UsuarioRepository implements Serializable {
    private static final long serialVersionUID = 1L;

    private EntityManager manager;

    @Inject
    public UsuarioRepository(EntityManager manager) {
        this.manager = manager;
    }

    public UsuarioModel porId(Long id) {
        return manager.find(UsuarioModel.class, id);
    }

    public List<UsuarioModel> todos() {
        TypedQuery<UsuarioModel> query = manager.createQuery("from UsuarioModel", UsuarioModel.class);
        return query.getResultList();
    }

    public UsuarioModel guardar(UsuarioModel usuario) {
        return this.manager.merge(usuario);
    }

    public void remover(UsuarioModel usuario) {
        this.manager.remove(usuario);
    }

    public UsuarioModel ValidaUsuario(String nomeUsuario,String senha){
        String Jpql = "Select u From UsuarioModel u Where u.nomeusuario = :usuario And u.senha = :senha";
        try {
            //Query que sera executada (Jpql)   
            TypedQuery<UsuarioModel> query = manager.createQuery(Jpql, UsuarioModel.class);
            //Parâmetros da Query
            query.setParameter("usuario", nomeUsuario);
            query.setParameter("senha", senha);
            //Retorna o Usuario se For Localizado
            return query.getSingleResult();
        } catch (Exception e) {
            return null;
        }

    }

}

and UserController class as below

package br.com.controller;

import java.io.Serializable;
import javax.inject.Inject;

import br.com.model.UsuarioModel;
import br.com.repository.UsuarioRepository;
import br.com.util.NegocioException;
import br.com.util.Transactional;

public class UsuarioController implements Serializable {
    private static final long serialVersionUID = 1L;

    @Inject
    private UsuarioRepository usuarioRepository;

    @Transactional
    public void salvar(UsuarioModel usuarioModel) throws NegocioException {
        if (usuarioModel.getNomeUsuario().isEmpty() ) {
            throw new NegocioException("Não é Possivel Salvar Funcionario sem Usuario");
        }
        this.usuarioRepository.guardar(usuarioModel);
    }

    @Transactional
    public void excluir(UsuarioModel usuarioModel) throws NegocioException {
        usuarioModel = this.usuarioRepository.porId(usuarioModel.getCodigo());
        if (usuarioModel.getNomeUsuario()!= null) {
            throw new NegocioException("Não é possível excluir um Funcionario sem Usuario");
        }
        this.usuarioRepository.remover(usuarioModel);
    }   

}

initializing EntityManager

with save

public UsuarioModel guardar(UsuarioModel usuario) {
    return this.manager.merge(usuario);
}

I made it understood in your explanation

usuarioModel = this.usuarioController2.salvar(this.usuarioModel);
        this.funcionarioModel.setUsuarioModel(usuarioModel);

But I still could not implement the code. If you can help me in any more.

follow the error

How to put a color on the tr of a dynamically selected Radio Error using monolog: PHP Fatal error: Class 'Monolog \ Logger' not found

The usuarioModel instance is probably in the detached state, meaning JPA does not know who it is because it is outside Persistence Context . In the excerpt:

//Salvar Insert Id do Objeto Usuário para a Tabela Funcionario Id_Usuario.
this.funcionarioModel.setUsuarioModel(usuarioModel);

You only add usuarioModel to your funcionarioModel , but it does not add to PersistenceContext .

According to the pattern you are following in your code, I believe you should have a usuarioController . If so, make sure that it has some method that adds usuarioModel to Persistence Context , for example, one that uses the merge method of EntityManager . So you could add it to Persistence Context and then add it to funcionarioModel like this:

this.usuarioModel = this.usuarioController.merge(this.usuarioModel);
this.funcionarioModel.setUsuarioModel(usuarioModel);

Edit:

The error occurs because usuárioModel that you are running merge has the nomeusuario field equal to null . To resolve this, substitute the invocation of the salvar(UsuarioModel usuarioModel) method of the UsuarioController class by invoking a method that calls the find method of the EntityManager class.

For the code that you put, you can invoke the porId method of the UsuarioRepository class or, if you want to keep the same layer structure, you could implement a method with this functionality in your UsuarioController class. In that case you would override this:

usuarioModel = this.usuarioController2.salvar(this.usuarioModel);
this.funcionarioModel.setUsuarioModel(usuarioModel);

So:

//O método porId da classe UsuarioController evocaria o metodo
//porId da classe UsuarioRepositoty que, por sua vez, evocaria
//o método find da classe EntityManager
usuarioModel = this.usuarioController2.porId(this.usuarioModel.getId());
this.funcionarioModel.setUsuarioModel(usuarioModel);
