How to remove Tableview lines even with search field using Javafx?

Eae personal, I am trying to put the option to clear Tableview in my project, but as I have implemented the search option whenever I try to clear Tableview is presented this error: Exception in thread "Javafx Application Thread" java.lang.Unsupportedoperationexception. If I comment my method responsible for the search the option to clear Tableview works perfectly. If possible you could kindly share some example of Tableview with research and option to delete, I’ve already googled but found no example with the two working options.

Search method I’m using:

public void pesquisaTableView(ObservableList<Dados> table, TextField filterField, TableView<Dados> tablev) {

    // Wrap the ObservableList in a FilteredList (initially display all data).
    FilteredList filteredData =  new FilteredList<>(table, b -> true);

    // 2. Set the filter Predicate whenever the filter changes.
    filterField.textProperty().addListener((observable, oldValue, newValue) -> {
        filteredData.setPredicate(employee -> {
            // If filter text is empty, display all persons.

            if (newValue == null || newValue.isEmpty()) {
                return true;
            } else {
                String lowerCaseFilter = newValue.toLowerCase();
                if (employee.getSituacao() != null) 
                {
                    if (employee.getSituacao().toLowerCase().contains(lowerCaseFilter) == true) {
                        return true;
                    }
                }

            return false; // Does not match.
        });
    });

    // 3. Wrap the FilteredList in a SortedList.
    SortedList<Dados> sortedData = new SortedList<>(filteredData);

    // 4. Bind the SortedList comparator to the TableView comparator.
    //    Otherwise, sorting the TableView would have no effect.
    sortedData.comparatorProperty().bind(tablev.comparatorProperty());

    // 5. Add sorted (and filtered) data to the table.
    tablev.setItems(sortedData);

}

You don’t need to put "solved" in the title. I know it’s common in many forums, but here it works different. You have already marked a reply as accepted (when you clicked ) and this is enough to indicate that it has been solved.

I was able to solve by placing all the data inside a global Observablelist and I cleaned the obsList lines with the clear() method. Below the code used:

    private ObservableList<DadosXml> obsListTableDados = FXCollections.observableArrayList();


// Metodo resposavel por filtrar por colunas a pesquisa
    public void pesquisaTableView(ObservableList<Dados> obsListDadosXml, TextField filterField, TableView<Dados> tablev) {

        // Wrap the ObservableList in a FilteredList (initially display all data).
        FilteredList<Dados> filteredData =  new FilteredList<>(obsListTableDados, b -> true);

        // 2. Set the filter Predicate whenever the filter changes.
        filterField.textProperty().addListener((observable, oldValue, newValue) -> {
            filteredData.setPredicate(employee -> {
                // If filter text is empty, display all persons.

                if (newValue == null || newValue.isEmpty()) {
                    return true;
                } 
                else {
                    String lowerCaseFilter = newValue.toLowerCase();
//                                    System.out.println("lowerCaseFilter "+lowerCaseFilter);
//                                    System.out.println(employee.getSituacao());
                    if (employee.getSituacao() != null) {
                        if (employee.getSituacao().toLowerCase().contains(lowerCaseFilter) == true) {
                            return true;
                        }
                    }                    
                }// fim else
                return false; // Does not match.
            });
        });

        // 3. Wrap the FilteredList in a SortedList.
        SortedList sortedData = new SortedList<>(filteredData);

        // 4. Bind the SortedList comparator to the TableView comparator.
        //    Otherwise, sorting the TableView would have no effect.
        sortedData.comparatorProperty().bind(tablev.comparatorProperty());

        // 5. Add sorted (and filtered) data to the table.
        tablev.setItems(sortedData);

    }


    // Metodo para limpar linhas TableView
    public  void limpaDados()
    {
obsListTableDados.removeAll(table.getItems());
}
