Combobox inside editable Table change selection when click to Column Sort

General
1

Greetings Vaadin Community
Please someone could help me with this.
I have a table. It’s in editable mode. One column is represented by Comboboxes.
When I click in the header to sort or insert a new row in the table. The data selected in the combo in the previous rows disappear.
Thanks for your help

table_2.setSelectable(true);
    table_2.setEditable(true);
    table_2.setImmediate(false);
    table_2.setFooterVisible(true);
    table_2.setColumnFooter("priceUSD", "Сумма");
    table_2.setTableFieldFactory(goodsTableFactory);
    table_2.setContainerDataSource(getTrlListContainer(""));
	
table_2.setVisibleColumns(new String[] {"clMSorteo", "mcolecciones", "menteros", "mboletos"});
    table_2.setColumnHeaders(new String[] { "Sorteo", "Colecciones", "Enteros", "Boletos" });
    
    table_2.setColumnExpandRatio("clMSorteo",2);
    table_2.setColumnExpandRatio("mcolecciones",1);
    table_2.setColumnExpandRatio("menteros",1);
    table_2.setColumnExpandRatio("mboletos",1);

    table_2.setColumnAlignment("mcolecciones",Table.ALIGN_RIGHT);
    table_2.setColumnAlignment("menteros",Table.ALIGN_RIGHT);
    table_2.setColumnAlignment("mboletos",Table.ALIGN_RIGHT);

What does getSorteos() do?

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
