Datatable with StickyHeader shows duplicate header in a tabview in Primefaces 8.0

I just upgraded from Primefaces 7.0 to Primefaces 8.0. I am seeing a duplicate header with a dataTable with StickyHeader inside a TabView when using the newer version. I did not see this behavior in 7.0. Isearched the forums and I did see a number of posts related to this issue. There is a solution posted by mertsincan on github (issue #1218) with a solution but it does not work. I downloaded the Primefaces showcase example and tried the solution posted by mertincan but it does not work. Below picture shows the behavior and I have an example file. I also checked all the link at github.com/primefaces/primefaces/… posted by Melloware on question Duplicate headers in primefaces data table

This is the same cars example from sticky on the showcase. Any direction/suggestions to fix this issue is very much appreciated. Thanks enter image description here Below is the viewfile

import java.io.Serializable;
import java.util.List;

import javax.annotation.PostConstruct;
import javax.faces.view.ViewScoped;
import javax.inject.Inject;
import javax.inject.Named;

import com.example.model.Car;
import com.example.service.CarService;

@Named
@ViewScoped
public class ScrollView implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = -1472033438497912037L;
    private List<Car> cars;

    @Inject
    private CarService service;

    @PostConstruct
    public void init() {
        cars = service.createCars(50);
    }

    public List<Car> getCars() {
        return cars;
    }

    public void setService(CarService service) {
        this.service = service;
    }

}

Below is the xhtml file. You can see the solution suggested by mertsincan on lines 10 and 11 in code : "mytabView.ui-tabs {position:static}

Solution

  • This was introduced in PF 8.0 because of this ticket: https://github.com/primefaces/primefaces/issues/5429

    Turns out zoom:1 was an old IE8 hack and since PF no longer supports IE8 we should not have converted it to transform: scale(1).

    This will be fixed in PF Elite 8.0.2 with this ticket: https://github.com/primefaces/primefaces/issues/5675
