Reset built-in sorting not working

[toniaca]

Hi,

I'm using the richfaces 4.3.0 version and I'm trying to reset the built-in Sorting.

I'm using the next code:

private SortOrder sortOrder;

public void limpiarOrdenDatosGrid(String identificador) {
     sortOrder = SortOrder.unsorted;
     UIExtendedDataTable table = (UIExtendedDataTable)FacesContext.getCurrentInstance().getViewRoot().findComponent("Formulario:"+identificador);
     for (UIComponent column : table.getChildren()) {
          (UIColumn) column).setSortOrder(sortOrder);
     }
}

The data go back to their original order, but the arrow does not return to its original state.

Thanks,
