Javafx: Re-sorting a column in a TableView

Question

I have a TableView associated to a TreeView. Each time a node in the TreeView is selected, the TableView is refreshed with different data.

I am able to sort any col

Answer 1

If you use the TableView.setItems() method, it appears to reset several aspects of the TableView. Leave the ObservableList in the TableView in place, clear its contents, and then add your new items. Then, TableView.sort() will still know which columns were previously sorted and it will work. Like this:

  tableView.getItems().clear();
  tableView.getItems().addAll(newTableData);
  tableView.sort();
