Hi, I have a DefaultDataTable with 5 columns, I want to be able to register
to an onclick method that fires when the user will click a specific row\cell
in the table.
In other words, I need to be able to open an edit screen when the user
clicks the row he wants to edit, and for that I need the row to be clickable
(or just the name cell) and I need to be able to be able to hook up to that
event.
My Code:
*Please bear in mind that I've only started developing in wicket a week ago
so if you see anything that doesn't make sense, please let me know so I can
fix it.*
*WebPage.java:*
> locationsEntityFacade =
> LookupHelper.getInstance().lookupLocationsEntityFacade();
> List locations = locationsEntityFacade.findAll();
> int count = locations.size();
>
> add(new Label("locationsCount", String.valueOf(count)));
>
> LocationsProvider locationsProvider = new LocationsProvider();
>
> IColumn[] columns = new IColumn[5];
> columns[0] = new PropertyColumn(new Model("Name"), "name", "name");
> columns[1] = new PropertyColumn(new Model("Address 1"),
> "streetAddress1", "streetAddress1");
> columns[2] = new PropertyColumn(new Model("Address 2"),
> "streetAddress2", "streetAddress2");
> columns[3] = new PropertyColumn(new Model("City"), "city", "city");
> columns[4] = new PropertyColumn(new Model("State"), "usState",
> "usState");
>
> DefaultDataTable table = new DefaultDataTable("datatable", columns,
> locationsProvider, 10);
> add(table);
* Location Provider:*
public class LocationsProvider extends SortableDataProvider{
>
> List list = new ArrayList();
> LocationsEntityFacadeLocal locationsEntityFacade;
>
> public LocationsProvider() {
> setSort("id", true);
> locationsEntityFacade =
> LookupHelper.getInstance().lookupLocationsEntityFacade();
> list = locationsEntityFacade.findAll();
> }
>
> public Iterator iterator(int first, int count) {
> List newList = new ArrayList();
> newList.addAll(list.subList(first, first + count));
> final String sortColumn = this.getSort().getProperty();

> int compare = ((Comparable)
