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

i'm experimenting openxava files stereotype , embedded class , finding strange error. first of all, if create record , attach bunch of files before saving first time, works. if i, however, first create record (temple), leave in embedded record (library) blank, save (saves successfully, says), go edit it, following message: "impossible execute add files action: member library.documents not found in model temple"

i have not been able find useful via google on this.

is i'm doing wrong or error in openxava library.

i'm using: openxava version 5.1.1 tomcat comes it: apache tomcat version 7.0.50 oracle 11g

here's temple , 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;     }  }
