Is there a CHANGEABLE ListProperty in JavaFX?

Is there a CHANGEABLE ListProperty in JavaFX? I need a ListProperty supprting add() and remove() methods, but I couldnt't find one. SimpleListProperty will throw UnsupportedOperationException.

All I found is to use the initializer to set the contents, but that's not what I need. I need to start with an empty Property end buld from there.

I cannot believe there's no such a thing; I must be blind, somehow. Can someone point me in the right direction, please?

Solution

  • It turns out ListProperty() is an empty wrapper.
    It does not initialize the wrapped ObservableList<>.
    This is absolutely unclean from documentation and the UnsupportedOperationException thrown is misleading (should be a NPE).
    Default constructor is useless in normal usage, use something like:

    ListProperty<String> xxx = new SimpleListProperty<>(FXCollections.observableArrayList());

    NOTE: Using a simple ObservableList does not work for me because I'm using Property methods (e.g.: getBean())
