RE: [Wicket-user] Listview: cannot instantiate the type

Very nice, bringing my mind back to the mail I wrote earlier(radio buttons with a twist) I guess I then could do the following, code might not be 100% accurate:

List maalinger = Arrays.asList(new String[][] { {"Aktuelle forløb fordelt på varighed","description"}, {"antal forløb","description"}, {"Forløb pr. berørt","description"}});

myList = new wicket.markup.html.list.ListView("maaling2",maalinger)

{

public void populateItem(wicket.markup.html.list.ListItem item)

{

String[] myItem=(String[]) item.getModelObject();

String radio= myItem[0];

String info= myItem[1];

item.add(new Radio("radio”, radio));

item.add(new Label("info",info));

}

};

form.add(myList);

Markup:

<tr>

</tr>

</table>

populateItem gives you the ListItem that is being created.

add your controls to the item in the populateItem method.

protected void populateItem(ListItem item) {
item.add(new Label("name", new PropertyModel( item.getModelObject(), "name")));
}

In your case that would be:
protected void populateItem(ListItem item) {
item.add(new Label("name", item.getModelObjectAsString()));
}

and in the markup:

<p wicket:id="list"><span wicket:id="name">text goes here</span></p>

Thanks, looking at the example again I see that.

However I have some difficulty seeing how I would be able to grab the contents of my List "forklaringer" from within the populateItem. Could you give an example?

ListView is abstract. You must implement the populateItem(...) method:

new ListView("list", forklaring) {
    public void populateItem(ListItem item) {
        // add stuff to item.
    }
};

Im having trouble instantiateing the Listview control, I get the error "Cannot Instiantiate the type ListView" . This is within these lines the errors occur:

private wicket.markup.html.list.ListView myList;

…

List forklaring = Arrays.asList(new String[] { "Aktuelle forløb fordelt på varighed", "antal forløb", "Forløb pr. berørt", "æ", "ø", "å" });

myList = new wicket.markup.html.list. ListView("list",forklaring);

…

This part is taken from the javadoc documentation:

add(new ListView("rows", listData)

which I belive is pretty similar to the code which I've written .
