EBean is not doing updates! it's trying to do inserts and failing
===

i have a simple User model like this:


    package models;
    
    import java.util.*;
    import javax.persistence.*;
    import play.db.ebean.*;
    
    @Entity
    public class User extends Model {
    
        	@Id
    	public Long id;
    	public String userName;
    	public String email;
    	public String workPlace;
    	public Date birthDate;
    	@Version
    	public Long version;
    
    	public static Finder<Long,User> find = new Finder<Long,User>(
    		Long.class, User.class
    	);
    
    	public Long getId() {
    		return id;
    	}
    
    	public void setId(Long id) {
    		this.id = id;
    	}
    
    	public String getUserName() {
    		return userName;
    	}
    
    	public void setUserName(String userName) {
    		this.userName = userName;
    	}
    
    	public String getEmail() {
    		return email;
    	}
    
    	public void setEmail(String email) {
    		this.email = email;
    	}
    
    	public String getWorkPlace() {
    		return workPlace;
    	}
    
    	public void setWorkPlace(String workPlace) {
    		this.workPlace = workPlace;
    	}
    
    	public Date getBirthDate() {
    		return birthDate;
    	}
    
    	public void setBirthDate(Date birthDate) {
    		this.birthDate = birthDate;
    	}
    
    	public Long getVersion() {
    		return version;
    	}
    
    	public void setVersion(Long version) {
    		this.version = version;
    	}
    }

in MySql there is already a record with id=1, version=1

i create a new model with the same id+version, change the userName

then i try the save() method

it fails with:

    javax.persistence.PersistenceException: ERROR executing DML bindLog[] error[Duplicate entry '1' for key 'PRIMARY']

what am i doing wrong?
inserting a new record works. so it looks to me like some ebean bug where its not recognizing that it should do an update. or is it some config that i forgot somewhere?

thanks
