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! } -- View this message in context: http://www.nabble.com/newbie-question-about-using-WizardStep%2C-help%21-thanks%21-tf4509850.html#a12862126 Sent from the Wicket - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
