Question

I have a datatable with search field and commandLink to sort. The commandLink that I use to trigger sorting is located not in column header but on the header of datatable. When I load my page and use only commandLink to sort everything works ok. Table sorts in two orders and I see result on my page. Problem appears when I search something in globalFilter. It also works, but after that I cant sort my table. I clear inputText of globalFilter and I cant sort table. To sum up, I see result of sorting only when I not use search field. Sort operation works but request not update the datatable. I put my code below. Maybe somebody knows how to solve it.

<ui:composition>
    <p:panel header="Moje pomiary" footer="#{msgs.footer}" id="myMeasurement">

        <h:form id="form" prependId="false">

             widgetVar="mTable"   
             emptyMessage="No files found with given criteria" filteredValue="#{myMeasurementTable.filteredMeasurement}" >

        </p:outputPanel>  
    </f:facet>

and part of my bean

@ManagedBean(name = "myMeasurementTable")
@ViewScoped
public class myMeasurementTable implements Serializable{


    private static final long serialVersionUID = -9193902657201234669L;
    private List<Measurement> measurement;
    private List<Measurement> filteredMeasurement;
    private boolean sortAscending = true;

    public myMeasurementTable() {
        measurement = new ArrayList<Measurement>();
        fillTable(measurement);
    }

    public String sortByName() {
        System.out.println("naciskam sortowanie");
        if (sortAscending) {
            Collections.sort(measurement, new Comparator<Measurement>() {

                @Override
                public int compare(Measurement m1, Measurement m2) {

                    return m1.getFileName().compareTo(m2.getFileName());

                }
            });
            sortAscending = false;
        } else {
            Collections.sort(measurement, new Comparator<Measurement>() {

                @Override
                public int compare(Measurement m1, Measurement m2) {
                    System.out.println(m2.getFileName());
                    return m2.getFileName().compareTo(m1.getFileName());

                }
            });
            sortAscending = true;
        }
        return null;
    }

Ok I found solution on primefaces forum. It’s simple. I only added oncomplete=”mTable.filter()” to commandButton and everything works as I want.
