c# - nhibernate returns an empty collection -

i have scenerio saving graph of objects , need retrieve later on in process. simple case of data manupulation really.

the problem after successful save of object , associated collection- indicated output insert statements- subsequent query same object returns empty collection associated collection. call flush() before that. strangely, closing , reopening application makes return populated collection.

i have mapping appointment class

<set name="workhours" inverse="true" cascade="all" lazy="true">   <key>     <column name="person" />   </key>   <one-to-many class="workhour" /> </set> 

here's code data retrieval

method1() {  dataaccessmanager.startoperation();         ienumerable<entity> q = getqueryprovider();         if (total > 0)         {             q = q.skip(startindex).take(total);         }         totalfound = q.count();         ilist<entity> list = q.tolist();         dataaccessmanager.endoperation();         return list; } protected override ienumerable<entity> getqueryprovider()     {         return dataaccessmanager.getqueryprovider<appointment>();     } 

and saving

        if (this.patient.appointments== null)             this.patient.appointments= new iesi.collections.generic.hashedset<appointment>();         this.patient.appointments.add(this);          if (this.doctor.appointments== null)             this.doctor.appointments= new iesi.collections.generic.hashedset<appointment>();         this.doctor.appoint.add(this);         entity ent = base.save();         return ent;        //the base call:       dataaccessmanager.startoperation();          try         {             entity t = dataaccessmanager.save<entity>(this);             dataaccessmanager.endoperation();             return t;         }         catch (nhibernate.hibernateexception ex)         {             //handling            }  //the data access save method   public t save<t>(t t) t : entity     {          try         {              currentsession.saveorupdate(t);              return t;   }  ///exception handling , stuff   } 

i end session commit() , disconnect() .

never mind it, wasn't setting associations before saving.
