imageview in tableview. JavaFX. Cant explain what is this? - imageview

Question

This is code mainController for my fxml form. Image in tableview work, but some strangeable.
Add first row - ok.
Add second: watch image in second from the start and first from the end.
Add third: watching in third row from the start and fourth from the end... etc..
What is this? data no add in those rows, but image adding. Where is problem?

The tableview and listview cells are reused to render different row data of the source list. Your problem probably lays on the updating of the cell item. Try this:
#Override
public void updateItem(CarPhoto item, boolean empty) {
super.updateItem(item, empty);
if (!empty && !item.equals(null)) {
imageview.setImage(new Image(item.getPhoto()));
}
else {
imageview.setImage(null);
}
System.out.println(item);
}
