MultiAutoCompleteTextField for Wicket

I need an AutoCompleteTextField for Wicket which can handle several autocomplete items separated by a comma.

Something like this: http://digitarald.de/project/autocompleter/1-1/showcase/delicious-tags/

I could resolve the problem by Ajax in wicket as the following

    TextArea partnersDB = new TextArea("partnersDB");
    String partnerKeeper;

    public String getPartnerKeeper() {
        return partnerKeeper;
    }
    public void setPartnerKeeper(String partnerKeeper) {
        this.partnerKeeper = partnerKeeper;
    }
    public String getMessageTypeKeeper() {
        return messageTypeKeeper;
    }
    public void setMessageTypeKeeper(String messageTypeKeeper) {
        this.messageTypeKeeper = messageTypeKeeper;
    }

    private void makePartnersAutoCompleter() {

        final List<String> allPartners = auditDAO.findAllPartnerIds();

        IAutoCompleteRenderer partnerRenderer = new AbstractAutoCompleteRenderer() {

            @Override
            protected String getTextValue(Object obj) {
                return getPartnerKeeper() + ((String) obj);
            }

            @Override
            protected void renderChoice(Object obj, Response r, String str) {
                r.write((String) obj);
            }

        };

        AutoCompleteBehavior autoCompleteBehavior = new AutoCompleteBehavior(partnerRenderer) {

            @Override
            protected Iterator<String> getChoices(String input) {
                int lastCommaIndex = input.lastIndexOf(';');
                String realInput = "";
                if (lastCommaIndex == -1) {
                    setPartnerKeeper("");
                    realInput = input;
                } else {
                    setPartnerKeeper(input.substring(0, lastCommaIndex) + ";");
                    realInput = input.substring(lastCommaIndex + 1);
                }

                List<String> completions = new ArrayList<String>();
                for (int i = 0; i < allPartners.size(); i++) {
                    String partner = allPartners.get(i);
                    if (partner.startsWith(realInput.toUpperCase()) || partner.startsWith(realInput.toLowerCase())) {
                        completions.add(partner + ";");
                    }
                }
                return completions.iterator();
            }

        };

                    partnersDB.add(autoCompleteBehavior);

    }

Wicket-extensions provides autocomplete features.

Add an AutoCompleteBehavior to the TextArea in the same fashion AutoCompleteTextField uses it.

For instance: 

TextArea t = new TextArea("area", new Model());
AutoCompleteBehavior<String> b = new AutoCompleteBehavior<String>(
            StringAutoCompleteRenderer.INSTANCE){
    @Override
    protected Iterator<String> getChoices(String input) {
        return getMyListElements().iterator();
    }
};
t.setOutputMarkupId(true);
t.add(b);
add(t);

If you are using Maven, just add the following dependency to start using wicket-extensions: 

<dependency>
    <groupId>org.apache.wicket</groupId>
    <artifactId>wicket-extensions</artifactId>
    <version>${wicket.version}</version>
</dependency>

EDIT Seeing that the question is about Multi autocomplete textfields, like the one in this example, you might find the following link useful: Wicket auto-complete text fields. There are a couple of components in there that seem to do just what you need.

You might also find this discussion and this one in the Apache Wicket User list useful. You'll find a couple of links there to projects that seem to also have this component: interwicket and WicketHub
