java.lang.IllegalStateException: Query argument " " not found in the list of parameters provided during query execution

I am new to JPA working with Netbeans and EclipseLink and I have created an entity Manager as well as a PK class, and a main class.

When I try to use the pre-generated names from Netbeans

@NamedQuery(name = "Company.findUser", query = "SELECT c FROM Company c WHERE c.companyPK.user = :user")
@NamedQuery(name = "Company.findPass", query = "SELECT c FROM Company c WHERE c.password = :password")

I am greeted with the error above

but 

    @NamedQuery(name = "Company.findAll", query = "SELECT c FROM Company c")

works and shows me everything......

Company:

@Entity
@Table(name = "Company")
@XmlRootElement
@NamedQueries({
    @NamedQuery(name = "Company.findAll", query = "SELECT c FROM Company c"),
    @NamedQuery(name = "Company.findUser", query = "SELECT c FROM Company c WHERE c.companyPK.user = :user"),
    @NamedQuery(name = "Company.findPass", query = "SELECT c FROM Company c WHERE c.password = :password")})
public class Company implements Serializable {
    private static final long serialVersionUID = 1L;
    @EmbeddedId
    protected CompanyPK companyPK;
    @Column(name = "Password")
    private String password;

CompanyPK:

@Basic(optional = false)
@Column(name = "User")
private String user;

AdminControl:

AdminControl:

  EntityManagerFactory emf = Persistence.createEntityManagerFactory("UploaderPU");
    EntityManager em = emf.createEntityManager();


    em.getTransaction().begin();
    Company c = new Company(new CompanyPK(userF.getText()),pass.getText());
    em.persist(c);
    em.getTransaction().commit();


       // TypedQuery<Company> query = em.createNamedQuery("Company.findUser", Company.class);
    Query q1 = em.createQuery("SELECT c FROM Company c WHERE c.companyPK.user = :user");
    System.out.println(q1.getSingleResult());

The above code is an error, but if I use Company.find all/"SELECT c From Company c" I will get all of the data in my db.

I know the data is also stored since I query my DB with netbeans each time to see the results.

What is interesting is that if I put the same data twice, i.e., user = a 2x I will get an error saying that the primary key is duplicated blah blah.

So I know it can read it, but why am I getting an error when it's not a duplicate?

Full error:

In line 100 of AdminResult, you are executing one of the named queries (your post does not show which, but it is probably Company.findUser). This query has a parameter :user in the JPQL. If q is your query, you need to do

q.setParameter("user", someValue);

to assign a value to that parameter at query execution time.

As an aside, it may be better to query for user and password in one query and making sure this returns exactly one hit.
