Wicket: 1.2.6

Is there a trick to getting a <table>'s data updated using Ajax (eg when a
DropDownChoice value changes - & without refreshing the whole page)?

I started with a <table> that got update by its ListView with no Ajax. That
worked well.

Now, I try to use a WebMarkupContainer to wrap the ListView so I can update
the <table> by Ajax. 

final ListView lines = new ListView("lv",myList){
    @Override
    protected void populateItem(ListItem item) {
        item.add(...);          // derive and add 1st name              
        item.add(...);          // derive and add 2nd name              
    }};
    WebMarkupContainer listContainer = new WebMarkupContainer("wmc");
    listContainer.add(lines);
    form.add(listContainer.setOutputMarkupId(true));

& the my most recent try at mark-up looks like:

<table border ="1" align="center">
        <thead>
                <tr>
                        <th>first name</th>
                        <th>last name</th>
                </tr>
        </thead>
        <tbody>
                <tr  wicket:id="wmc">
                        <td wicket:id="fN">firstName</td>
                        <td wicket:id="lN">lastName</td>
                </tr>
        </tbody>
</table>
