Entry in Listview losing focus immediately after the I focuses

Hi,

I have used ListView with custom ViewCell's that contain Entry, but Entry text box losing focus immediately after the I focuses it. It also does not bring up a keyboard when pressed.

I have checked several links but I didn't get proper solution, they mansion that it is bug of Xamarin form

I am using Xamarin form version - 2.0.0.6490.

Below is the code -
Test.xaml.cs file code -

List objPendingList1 = new List();
objPendingList1.Add(new PendingUpdate() { Id = "1", Status = "0", CanEdit = true, Due = DateTime.Now, Start = DateTime.Now, Item = new      PendingUpdateItem() { Id = "11", Name = "test" } });
objPendingList1.Add(new PendingUpdate() { Id = "2", Status = "0", CanEdit = true, Due = DateTime.Now, Start = DateTime.Now, Item = new PendingUpdateItem() { Id = "12", Name = "test1" } });

var dataTemplate = new DataTemplate(typeof(PendingUpdateCell));
        var listView = new ListView();
        Device.BeginInvokeOnMainThread(() =>
        {
            listView.ItemsSource = objPendingList1;
            listView.ItemTemplate = dataTemplate;
            listView.HasUnevenRows = true;
            Content = listView;
        });

CustomViewCell -
public class PendingUpdateCell: ViewCell
{
public PendingUpdateCell()
{
int tapCount = 0;
string selectedStatus = "";
string selectedDate = "";
string addedComment = "";
var tabImage = new Image()

    View = layout;
}

}

another file contain classes -

public class PendingUpdate
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("start")]
public DateTime Start { get; set; }
[JsonProperty("due")]
public DateTime Due { get; set; }
[JsonProperty("item")]
public PendingUpdateItem Item { get; set; }
[JsonProperty("status")]
public string Status { get; set; }
[JsonProperty("canEdit")]
public bool CanEdit { get; set; }
public string StatusText { get; set; }
}

public class PendingUpdateItem
{
[JsonProperty("id")]
public string Id { get; set; }

[JsonProperty("name")]
public string Name { get; set; }

}

commentEntry - does not work here.
Please suggest me.
