Update autoComplete JavaFx? - binding

Question

I'm currently working on a JavaFX project.I'm using Autcomplete TextField of ControlFx .Each time i add new rows in database table, it should to update Autocomplete ,i did this but my problem is showing double Context-Menu ,we can say double autocompletes because i call method that create autocomplete each adding of new elements in table.
When i click a tab editBill i call this method :
public void showEditBill() {
if (!BillPane.getTabs().contains(EditBillTab)) {
BillPane.getTabs().add(EditBillTab);
}
SingleSelectionModel<Tab> selectionModel = BillPane.getSelectionModel();
selectionModel.select(EditBillTab);
/*it should remove the old autocomplete from textfield*/
pushBills(); //Call for cheking new items
}
pushBills method () :
public void pushBills() {
ArrayList list = new ArrayList<>();
bills = new BillHeaderDao().FindAll();
for (int i = 0; i < bills.size(); i++) {
list.add(bills.get(i).getIdClient());
}
//How can i remove the old bind before bind again
autoCompletionBinding = TextFields.bindAutoCompletion(SearchBill, SuggestionProvider.create(list));
}
How i can remove the old autocomplete and bind new automplete?

Answer 1

Just in any case if you need to keep instance of AutoCompletionTextFieldBinding object, thus avoiding use of:
autoCompleteBinding = TextFields.bindingAutoCompletion(TextField,List);
, which will change the instance, we could go a little bit deeper and use this:
// let's suppose initially we have this possible values:
Set<String> autoCompletions = new HashSet<>(Arrays.asList("A", "B", "C"));
SuggestionProvider<String> provider = SuggestionProvider.create(autoCompletions);
new AutoCompletionTextFieldBinding<>(textField, provider);
// and after some times, possible autoCompletions values has changed and now we have:
Set<String> filteredAutoCompletions = new HashSet<>(Arrays.asList("A", "B"));
provider.clearSuggestions();
provider.addPossibleSuggestions(filteredAutoCompletions);
So, through SuggestionProvider, we have "updated" auto completion values.
To avoid doubling of suggestions menu, don't use again (for the 2nd time):
TextFields.bindAutoCompletion(..)

Answer 2

In order to provide updates to the auto-complete suggestion list, retain a reference to the SuggestionProvider and update the suggestion provider instead:
TextField textField = new TextField();
SuggestionProvider suggestionProvider = SuggestionProvider.create(new ArrayList());
new AutoCompletionTextFieldBinding<>(textField, suggestionProvider);
When you want to update the suggestion list:
List<String> newSuggestions = new ArrayList();
//(add entries to list)
suggestionProvider.clearSuggestions();
suggestionProvider.addPossibleSuggestions(newSuggestions);

Answer 3

This will do the trick:
Instead of: TextFields.bindAutoCompletion(textField, list);
, try this:
List<String> strings = new ArrayList<>();
Then create binding between your textField with the list through:
new AutoCompletionTextFieldBinding<>(textField, SuggestionProvider.create(strings));
So any changes, including removing, from the list, will be reflected in the autoCompletion of the textField;
And you will have dynamic filtering of suggestions, showed in pop-up, when user enter some text in textField;

Answer 4

I had the same problem some time ago I try to do as #MaxKing mentions, but it didnt work. I managed to give it a solución even though I don't think it's the right way.
// Dispose the old binding and recreate a new binding
autoCompleteBinding.dispose();
autoCompleteBinding = TextFields.bindingAutoCompletion(TextField,List);
try this:
public void pushBills() {
ArrayList list = new ArrayList<>();
bills = new BillHeaderDao().FindAll();
for (int i = 0; i < bills.size(); i++) {
list.add(bills.get(i).getIdClient());
}
autoCompletionBinding.dispose();
autoCompletionBinding = TextFields.bindAutoCompletion(SearchBill, SuggestionProvider.create(list));
}
