Igor Vaynberg resolved WICKET-2922.
-----------------------------------

      Assignee: Igor Vaynberg
    Resolution: Won't Fix

autocomplete is not meant to pick out an object from a list, only to submit a string. what does your converter do if the user enters a value that cannot be converted back to one of your objects?

for such usecases see the objectautocomplete component in wicketstuff

> When using AutoCompleteTextField, and returning POJOs from the getChoices override, and then rendering the POJO to text value through a IAutoCompleteRenderer, unless you also provide a Converter to the component, it is not possible to provide fully types parameters to the constructor.
> I.E.:
> new AutoCompleteTextField<MyPojo>("compoonentId", new PropertyModel<String>(this, "myPojoName"), new MyPojoRenderer<MyPojo>())
> {
>     @Override
>     protected Iterator<MyPojo> getChoices(final String input) {
>         return getMyPojoChoices();
>     )
> }
> This will not compile, as the PropertyModel MUST be of type MyPojo, but unless you provide a Converter to convert the text choice back to the POJO instance, the model _cannot_ actually be of any type other than String.
> I would like to see AutoCompleteTextField to be changed so that you can type it like:
> AutoCompleteTextField<MyPojo, MyPojo>
> AutoCompleteTextField<MyPojo, String>
> Depending on whether you are handling the conversion via a getConverter(Class<?>) override, or outside the AutoCompleteTextField.
