Below is my code and I would greatly appreciate if someone can point out the
problem:

I modifed the code and I can display the checkbox. I have a remove button
that will remove all the checked events. How can I get the checked events from
the dataTable object?
Event.java
public Event() {
FeedbackPanel feedback = new FeedbackPanel("feedback");
add(new NewListForm(feedback));
add(feedback);
}
private class NewListForm extends Form {
public NewListForm(IFeedback feedback) {
super("form");
final List columns = new ArrayList();
columns.add(new PropertyColumn(new Model("Id"),
"eventId", "eventId"));
columns.add(new PropertyColumn(new Model("Event
Description"), "description",
"description"));
columns.add(new PropertyColumn(new Model("Start Date"),
"startDate",
"startDate"));
columns.add(new PropertyColumn(new Model("End Date"),
"endDate"));
columns.add(new AbstractColumn(new Model("Selected"))
{
public void populateItem(Item
cellItem, String componentId, IModel model)
{
cellItem.add(new
ActionPanel(componentId, model, cellItem));
}
});
EventsPage.this.table = new DefaultDataTable("table",
columns, new
EventSortableDataProvider(), 8);
add(EventsPage.this.table);
add(new Button("removeEvent") {
@Override
public void onSubmit() {
//How will I get the selected rows?
setResponsePage(new EventsPage("Removed
the Selected Events"));
}
});
}
}
class ActionPanel extends Panel
{
public ActionPanel(String id, final IModel model, final Item
item)
{
super(id, model);
add(new CheckBox("checked", new AbstractCheckBoxModel()
{
@Override
public void setSelected(Component component,
boolean sel) {
((EventDetachableModel)
model).setChecked(sel);
}
@Override
public boolean isSelected(Component component) {
return ((EventDetachableModel)
model).isChecked();
}
}));
}
}
}
