Hi everyOne,
when i try to get a list of object in "Societe" class 


i'm getting this exception
 

LazyInitializationException] failed to lazily initialize a collection of role: com.protid.prosa.shared.model.bo.Commune.soumission, no session or session was closed
[INFO] org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.protid.prosa.shared.model.bo.Commune.soumission, no session or session was closed

Notice that the class Societe have an attribute of type Adresse. the adresse has an attribute Commune . A set of "Soumission" are declared in Commune class by the annotation OneToMany like this

@OneToMany(fetch = FetchType.LAZY, mappedBy="commune",targetEntity=com.protid.prosa.shared.model.bo.Soumission.class)
@Cascade(value = {CascadeType.ALL })
private Set<Soumission> soumission =new HashSet<Soumission>();

public Set<Soumission> getSoumission(){
    return soumission;
}
 
}

i don't get where is the problem because i'm not looking  for the "soumission " objects in the Commune class !!!


here is my rpc cal function

private void getCompany(){
       
        SocieteServiceAsync rpc=clientFactory.getSocieteservicerpc();
          
 
        AsyncCallback<List<Societe>> callback = new AsyncCallback<List<Societe>>() {           
            public void onFailure(Throwable caught) {
                       
                       }
                     
                     
                    public void onSuccess(List<Societe> result) {
                         
                          if(result!=null){
                              societe=result.get(0);
                               result.get(0).getNomsociete();
                       
                          }
                    
                    }
                    };
                   
                rpc.list(callback);
 
                    
    }

Please help,

Thank you
