Direct Known Subclasses:

DefaultCssAutoCompleteTextField

public abstract class AutoCompleteTextField<T>
extends TextField<T>

An implementation of a textfield with the autoassist ajax behavior AutoCompleteBehavior.

An IAutoCompleteRenderer is used for rendering of choices. To convert input back into a non-String type you will have to provide a custom IConverter, either by overriding Component.getConverter(Class) or by setting a suitable IConverter on the application's ConverterLocator.

Note that you must add your own CSS to make the suggestion display properly, see DefaultCssAutoCompleteTextField for an example.
