Re: [Wicket-user] RE: Resetting a Form

[Johan Compagner]

what is that:

propertyModel = new PropertyModel(accountPage.getUser(),
            RequiredFieldContainer.CLASSIFIED_ACCOUNT_TYPE);

where is that model used?

and why are you making a new model why net just set the model object on the form itself?
form.setModelObject(user)

At wit's end here so I'm going to post my code.  Can't for the life of me figure out why the form won't reset, even when I re-initialize the underlying model object.

 

Code follows:

 

AccountPage.java

 

public class AccountPage extends DefaultPage
{
   /* The user to edit, or null (for a new user) */
   private User user;

   public AccountPage(PageParameters parameters)
   {
      super("Account");

      String accountId = parameters.getString("accountId");

      User theUser = UserProvider.getInstance().getUserByAccountID(accountId);

 

      /* The is a new account, new up a User as our Model object */
      if (theUser == null)
      {
         theUser = new User();
      }

 

      setUser(theUser);

      addInstructions();

      addAccountPanel();
   }

 

...

 

 public void addAccountPanel()
   {
      add(new AccountPanel("accountPanel", this));
   }

 

AccountPanel.java

 

public AccountPanel(String id, AccountPage accountPage)
   {
      super(id);

 

      this.accountPage = accountPage;

 

      model = new BoundCompoundPropertyModel(accountPage.getUser());

 

      propertyModel = new PropertyModel(accountPage.getUser(),
            RequiredFieldContainer.CLASSIFIED_ACCOUNT_TYPE);

 

      accountForm = new Form("accountForm", model);

 

      add(accountForm);

 

...

 

down in the submit button's onSubmit (still inside AccountPanel.java)...

 

Button submitButton = new Button("submitButton", new Model())
      {
         protected void onSubmit()
         {
            /*
             * See below comment in the cancel button concerning the null
             * response page
             */
            cancelResponsePage();

            /*
             * If user already exists, update the user. Otherwise create the
             * user.
             */

            if (UserProvider.getInstance().userExists(accountPage.getUser()))
            {
               UserProvider.getInstance().updateUser(accountPage.getUser(),
                     true);

               resetForm();

               getPage().getResponse().redirect(
                     (String)accountPage.getWp2fSession().getHttpSession()
                           .getAttribute(SessionConstants.ORIGINAL_REFERRER ));
            }
            else
            {

               UserProvider.getInstance().addUser(accountPage.getUser());
               /*
                * Reprint, review, whatever. Shows instructions, pops up the
                * SAAR.
                */

               String response = "/reprintUserRegistration.jsp?token="
                     + accountPage.getUser().getToken() + "&accountType="
                     + accountPage.getUser ().getAccountType();

               resetForm();

               getPage().getResponse().redirect(
                     accountPage.getContextPath() + response);
            }
         }
      };

 

...

 

 /**
    * Reset the model of the page, form, etc.
    *
    * Subsequent visits to the page should show up with no data already entered.
    */
   private void resetForm()
   {
      User user = new User();

      model = new BoundCompoundPropertyModel(user);

      accountForm.setModel(model);

   }

 

 

 

Any insight would be much appreciated :)
