I had the same issue in JavaFX 8 (with ComboBox too). I was able to get the same functionality by removing the item then adding a new one at the same location.

Example:

This gets selected item, creates a new item, then calls the replace method:

Channel selected = channelChoiceBox.getSelectionModel().getSelectedItem();
Channel newChan = new Channel("Example", "Channel");
replaceChannel(newChan, selected);

This replaces the selected channel with the new one, effectively editing it:

private void replaceChannel(Channel newChan, Channel oldChan) {
    int i = channelChoiceBox.getItems().indexOf(oldChan);
    channelChoiceBox.getItems().remove(oldChan);
    channelChoiceBox.getItems().add(i, newChan);
    channelChoiceBox.setValue(newChan);
}

It's not ideal, but does the job.
