I have a UsersPanel that contains a UsersTablePanel
and a delete link (Ajax).
UsersTablePanel contains a DataTable (Ajax) with the
first column only for selection (checkboxes), and a
method getSelectedIds():List<Long>.
The user flow is very simple: check (select) some rows
from table and click on delete link.
I want to popup a confirmation message like "Remove X
users ?" where X is number of selected rows on delete.
How can I do that?
I have tried something like this but without success:
public class UsersPanel extends Panel {
@SpringBean(name = "userService")
private UserService userService;
private UsersTablePanel usersTablePanel;
public UsersPanel(String id) {
super(id);
// add users panel with the users table
add(usersTablePanel = new
UsersTablePanel("usersTablePanel"));
// add delete link
add(new AjaxLink("deleteUsers") {
@Override
public void onClick(AjaxRequestTarget target) {
List<Long> selectedIds =
usersTablePanel.getSelectedIds();
int size = selectedIds.size();
System.out.println(">" + size);
if (size > 0) {
userService.deleteUsers(selectedIds);
target.addComponent(usersTablePanel.getDataTable());
}
}
@Override
protected IAjaxCallDecorator getAjaxCallDecorator()
{
return new AjaxCallDecorator() {
@Override
public CharSequence
decorateScript(CharSequence
script) {
List<Long> selectedIds =
usersTablePanel.getSelectedIds();
int size = selectedIds.size();
System.out.println(">>" + size);
if (size > 0) {
return
"if(!confirm('Remove " + size +
" users ?'))
return false;" + script;
}
return script;
}
};
}
});
}
}
Thanks in advance,
Decebal
