Description

Currently there is no easy way to access the AutoCompleteBehavior of the AutoCompleteTextField. This is useful when dynamically enabling/disabling the behavior (among other reasons).

The current code is:

	public AutoCompleteTextField(String id, IModel model, Class type,
		IAutoCompleteRenderer renderer, AutoCompleteSettings settings)
	{
		super(id, model, type);
		// this disables Firefox autocomplete
		add(new SimpleAttributeModifier("autocomplete", "off"));

		add(new AutoCompleteBehavior(renderer, settings)
		{

			private static final long serialVersionUID = 1L;

			protected Iterator getChoices(String input)
			{
				return AutoCompleteTextField.this.getChoices(input);
			}

		});
	}

One solution to this is to extract the creation of the AutoCompleteBehavior to a method:

	public AutoCompleteTextField(final String id, final IModel model, final Class<?> type, final IAutoCompleteRenderer renderer, final AutoCompleteSettings settings) {
		super(id, model, type);
		// this disables Firefox autocomplete
		add(new SimpleAttributeModifier("autocomplete", "off"));

		final AutoCompleteBehavior autoCompleteBehavior = createAutoCompleteBehavior(renderer, settings);
		if (autoCompleteBehavior == null) {
			throw new NullPointerException("Auto complete behavior cannot be null");
		}
		add(autoCompleteBehavior);
	}

	protected AutoCompleteChoiceBehavior createAutoCompleteBehavior(final IAutoCompleteRenderer renderer, final AutoCompleteSettings settings) {
		return new AutoCompleteChoiceBehavior(renderer, settings);
	}

	public class AutoCompleteChoiceBehavior extends AutoCompleteBehavior {
		public AutoCompleteChoiceBehavior(final IAutoCompleteRenderer renderer, final AutoCompleteSettings settings) {
			super(renderer, settings);
		}
		protected final Iterator<?> getChoices(final String input) {
			return AbstractAutoCompleteTextField.this.getChoices(input);
		}
	}
