Apache Wicket TextField - wicket

Question

Good day!
I create some Table:
List<IColumn<User, String>> columns = new ArrayList<>();
columns.add(new AbstractColumn<User, String>(new Model<String>("")) {
#Override
public void populateItem(Item<ICellPopulator<User>> cellItem, String componentId, IModel<User> rowModel) {
cellItem.add(new Link<String>(componentId) {
#Override
public void onClick() {
System.out.println("editors" + rowModel.getObject().getName());
PageParameters parameters = new PageParameters();
parameters.add("id", rowModel.getObject().getId());
add(new EditPanel("panel", rowModel));
}
#Override
public IMarkupFragment getMarkup() {
return Markup.of("<div wicket:id='cell'> edit </div>");
}
});
}
When I click on cell into Table, cell markup "Edit", I create some Panel:
public class EditPanel extends Panel {
public EditPanel(String id, IModel<User> model) {
super(id, model);
User user = model.getObject();
if (user == null) {
user = new User();
}
List<UserRole> list = Arrays.asList(UserRole.values());
Form<?> form = new Form("form", new CompoundPropertyModel(user));
TextField<String> userName = new TextField<String>("name");
};
add(new FeedbackPanel("feedback"));
add(form);
form.add(userName);
}
}
How can I set value to
TextField userName = new TextField("name");
from my model, or if model == null, set any text what I need?
Thanks!

If you use Wicket 7 or older then you may use :
TextField<String> userName = new TextField<String>("name", new PropertyModel(model, "username"));
assuming that username is a property of User.
With Wicket 8.x you can use LambdaModel instead.

Heyy,
I think the problem is because you are passing the object and not the model.
The right way is passing with CompoundPropertyModel, like you do. It`s better then PropertyModel in this case.
Try doing this:
...
if (model.getObject() == null) {
model.setObject(new User());
}
Form<?> form = new Form("form", new CompoundPropertyModel(model));
...
Hope help you.
