java - Ebean record fails to pick up on a relationship -

i having trouble ebean/play not picking licks between tables.

i have 3 tables, users, groups , usersgroups (bridge).

i have record in each table , when pick users record, object has access associated usersgroups records. when try same groups linked usersgroups object empty. have little experience orms , have no idea how can debug issue.

users class:

@entity public class users extends model {      @id     @generatedvalue(strategy = generationtype.auto)     public long intuserid;      @javax.persistence.column(length = 50, unique = true)     @constraints.required     public string strusername;      @onetomany(mappedby = "user", fetch = fetchtype.eager, cascade = cascadetype.all)     public list<sessions> session;      @onetomany(mappedby = "member", cascade = cascadetype.all)     public list<usersgroups> memberofgroups;       @javax.persistence.column(length = 50)     public string strfirstname;      @javax.persistence.column(length = 50)     public string strlastname;      @javax.persistence.column(length = 50, unique = true)     @constraints.required     public string stremail;      @formats.datetime(pattern = "dd/mm/yyyy")     public date tsregistrationdate = new date();      public string strpasswordhash;      public static finder<long, users> find = new finder(long.class, users.class); } 

groups class:

@entity public class groups extends model {      @id     @constraints.required     @column(unique = true)     @generatedvalue(strategy = generationtype.auto)     public long intgroupid;      @transient     public long inttoken() {         return this.intgroupid + 100000;     }      @onetomany(mappedby = "group", cascade = cascadetype.all)     public list<usersgroups> usersgroups;      @constraints.required     @formats.datetime(pattern = "dd/mm/yyyy")     public date tscreated = new date();      @constraints.required     @javax.persistence.column(length = 2)     public long inttype;      @constraints.required     @javax.persistence.column(length = 2)     public long intstatus = (long) 1;      @constraints.required     @javax.persistence.column(length = 50)     public string strname;      @constraints.required     public boolean blpublic;      public static finder<long, groups> find = new finder(long.class, groups.class); } 

bridge class:

@entity public class usersgroups extends model {      @manytoone(cascade=cascadetype.all)     @joincolumn(name = "int_user_id")     public users member;      @manytoone(cascade=cascadetype.all)     @joincolumn(name = "int_group_id")     public groups group;      public int type;       public static finder<long, usersgroups> find = new finder(long.class, usersgroups.class);    } 

now issue:

system.out.println("group: "+ group.intgroupid); system.out.println("ugroup: "+ ebean.group(usersgroups.class ).where().eq("int_group_id", group.intgroupid).findrowcount()); system.out.println(group.usersgroups.size()); 

prints:

group: 12 ugroup: 1 0 

from gather 1. groups object found, 2. associated record in bridge table found, 3. ebean fails pick link.

help appreciated.
