OpenXava Impossible to execute Add files action Member not found in model - openxava

Question

I'm experimenting with OpenXava files stereotype and embedded class and finding a strange error. First of all, if I create a record and attach a bunch of files to it before saving it for the first time, everything works. If I, however, first create a record (Temple), leave everything in the embedded record (Library) blank, save (saves successfully, it says), then go back to edit it, I get the following message: "Impossible to execute Add files action: Member library.documents not found in model Temple"
I have not been able to find anything useful via google on this.
Is this something I'm doing wrong or an error in OpenXava library.
I'm using: OpenXava version 5.1.1
Tomcat that comes with it: Apache Tomcat Version 7.0.50
Oracle 11g
Here's my Temple and the inner Library class:
package org.openxava.zen.model;
import javax.persistence.*;
import org.openxava.annotations.*;
#Entity
public class Temple
{
#Id #Column(length=3) #GeneratedValue #ReadOnly
private int id;
#Version
private Integer version;
#Column(length=50)
private String name;
#Stereotype("IMAGES_GALLERY")
private String photos;
#Column
private String address;
#Embedded
private Library library;
#Embeddable
public static class Library
{
#Stereotype("FILES")
#Column(length=32)
private String documents;
public Admittance getAdmittance() {
return admittance;
}
public void setAdmittance(Admittance admittance) {
this.admittance = admittance;
}
#Column
private Admittance admittance;
public enum Admittance {MEMBERS_ONLY, COMMUNITY, EVERYONE};
public String getDocuments()
{
return documents;
}
public void setDocuments(String documents)
{
this.documents = documents;
}
}
public Library getLibrary() {
return library;
}
public void setLibrary(Library library) {
this.library = library;
}
public Integer getVersion() {
return version;
}
public void setVersion(Integer version) {
this.version = version;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhotos() {
return photos;
}
public void setPhotos(String photos) {
this.photos = photos;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
}
