Table BeanItemContainer not compatible with footer

Vaadin 6 / 7 / 8
1

I have a table which uses BeanItemContainer to set the datasource, then when i want to add the footer, it doesn’t work.

In view, initialize the table container:

informationTableContainer = new BeanItemContainer<>(Info.class);
informationTable.setContainerDataSource(informationTableContainer);

Then, add the information and add the footer:

view.getInformationTable().setFooterVisible(true);
view.getInformationTable().setColumnFooter(view.NAME, view.TOTAL_ROW);
view.getInformationTable().setColumnFooter(view.NUMBER, String.valueOf(total));
view.getInformationTable().setColumnFooter(view.TOTAL, String.valueOf(total2));
view.getInformationTable().setPageLength(view.getInformationTable().size());

The content is correct, but the footer is not shown in the table.
Can you tell me why? Thank you.

Hi,

Your code isn’t complete. So, it’s complicated to help you.

Here is an functional example (tested with Vaadin 7.4.7) :
Person class

public class Person {

    private String name;
    private String firstname;
    
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getFirstname() {
        return firstname;
    }
    
    public void setFirstname(String firstname) {
        this.firstname = firstname;
    }
}

Testvaadin7UI class

public class Testvaadin7UI extends UI {

    @WebServlet(value = "/*", asyncSupported = true)
    @VaadinServletConfiguration(productionMode = false, ui = Testvaadin7UI.class)
    public static class Servlet extends VaadinServlet {
    }

    @Override
    protected void init(VaadinRequest request) {
        BeanItemContainer<Person> container = new BeanItemContainer<Person>(Person.class);
        Table t = new Table();
        setContent(t);
        
        Person p = new Person();
        p.setName("dupond");
        p.setFirstname("fany");
        
        Person p2 = new Person();
        p2.setName("durant");
        p2.setFirstname("jacques");
        
        container.addItem(p2);
        container.addItem(p);
        
        t.setFooterVisible(true);
        t.setColumnFooter("name", "lastname");
        t.setColumnFooter("firstname", String.valueOf(container.size()));
        
        t.setContainerDataSource(container);
        
    }

}
