Combobox inside editable Table change selection when click to Column Sort

What does getSorteos() do?

Regards
Thanks for responding
This is the code

@SuppressWarnings("rawtypes")

private List getSorteos(){
List<ClMSorteoBean> clMSorteoBean = new ArrayList<ClMSorteoBean>();

StringBuffer sb = new StringBuffer();

sb.append("Select a ");
sb.append("From ClMSorteo a ");

List listobjects = mainComponent.getJpaPersistenceManagerService().getObjects(sb.toString());

for(int i=0;i<listobjects.size();i++){
ClMSorteo u = (ClMSorteo) listobjects.get(i);
String d = u.getClMProducto().getVdescripcion()+" "+u.getVtipo()+' '+u.getInumero()+' '+u.getDfecha();
clMSorteoBean.add(new ClMSorteoBean(u.getIidsorteo() ,d , u));

}

return clMSorteoBean;

}

public class ClMSorteoBean {

private int iidsorteo;
private String descripcion;
private ClMSorteo clMSorteo;

public ClMSorteoBean(int iidsorteo, String description,ClMSorteo clMSorteo) {

this.iidsorteo = iidsorteo;
this.descripcion = description;
this.clMSorteo = clMSorteo;

}

public int getIidsorteo() {
return iidsorteo;
}

public void setIidsorteo(int iidsorteo) {
this.iidsorteo = iidsorteo;
}

public String getDescripcion() {
return descripcion;
}

public void setDescripcion(String descripcion) {
this.descripcion = descripcion;
}

public ClMSorteo getClMSorteo() {
return clMSorteo;
}

public void setClMSorteo(ClMSorteo clMSorteo) {
this.clMSorteo = clMSorteo;
}

@Override
public int hashCode() {
final int prime = 31;
int result = 1;
result = prime * result
+ ((clMSorteo == null) ? 0 : clMSorteo.hashCode());
result = prime * result
+ ((descripcion == null) ? 0 : descripcion.hashCode());
result = prime * result + iidsorteo;
return result;
}

@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
ClMSorteoBean other = (ClMSorteoBean) obj;
if (clMSorteo == null) {
if (other.clMSorteo != null)
return false;
} else if (!clMSorteo.equals(other.clMSorteo))
return false;
if (descripcion == null) {
if (other.descripcion != null)
return false;
} else if (!descripcion.equals(other.descripcion))
return false;
if (iidsorteo != other.iidsorteo)
return false;
return true;
}

}

After reading several forums can resolve the problem, let part of the code here in case anyone has the same problem
This code resolve
Combobox select/setValue and
Data selected in the combo in the previous rows disappear where click in the header to sort or insert a new row in the table.
Good Luck
