Yep, you need to work with models. For instance:

RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField("receivedNumberOfBoxes", Integer.class, new
PropertyModel(delivery, "receivedNumberOfBoxes"));
add(receivedNumberOfBoxesTextField);

or:

setModel(new CompoundPropertyModel(delivery));
RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField("receivedNumberOfBoxes", Integer.class);
add(receivedNumberOfBoxesTextField);

newbie question about using WizardStep, help! thanks!

[raybristol]

Hi experts,

I want to implement a wizard, user need to input some data, I can do it with
a single page using form, but I don't know how to do it in wizard, I put a
couple of input textfield etc. then I get a error:

java.lang.IllegalStateException: Attempt to set model object on null model
of component: wizard:form:view:expectedNumberOfBoxes

Note: expectedNumberOfBoxes is the first textfield I declared in the java
class, after googling a few hours(not too much information) I think I need
to setup a 'model'? but I probably need more details how... my code is like:

public class DeliveryDetails extends WizardStep {


public DeliveryDetails(Delivery delivery, String title, String content){
super(title, content);

RequiredTextField expectedNumberOfBoxesTextField = new
RequiredTextField("expectedNumberOfBoxes", Integer.class);
add(expectedNumberOfBoxesTextField);

RequiredTextField receivedNumberOfBoxesTextField = new
RequiredTextField("receivedNumberOfBoxes", Integer.class);
add(receivedNumberOfBoxesTextField);

}


Thansk a million for your help as this really difficult to solve by
googling! thanks!
