Hi,
we've got several examples in our logs of properties of the model
being set to null even though the textfield is set to required.
I have NO idea how on earth this can happen - its just doesn't make
sense - and its really frustrating me!!
here's an example:
Caused by: java.lang.NullPointerException
at org.apache.commons.codec.digest.DigestUtils.md5(DigestUtils.java:86)
at
org.apache.commons.codec.digest.DigestUtils.md5Hex(DigestUtils.java:108)
at
hub.app.wicket.admin.ChangePasswordPage$1.onSubmit(ChangePasswordPage.java:49)
at
org.apache.wicket.markup.html.form.Form.delegateSubmit(Form.java:1518)
...
Form<User> form = new Form<User>("form", new
CompoundPropertyModel<User>(new HibernateEntityModel<User>(User.class,
u.getId()))) {
@Override
protected void onSubmit() {
User u = getModelObject();
u.setPassword(DigestUtils.md5Hex(u.getPassword());
userDAO.save(u);
setRedirect(true);
setResponsePage(HubApplication.get().getHomePage());
}
};
form.add(new Label("email"));
PasswordTextField password = new PasswordTextField("password");
form.add(password);
PasswordTextField repeatPassword = new
PasswordTextField("repeatPassword");
repeatPassword.setModel(password.getModel());
form.add(repeatPassword);
form.add(new EqualPasswordInputValidator(password,
repeatPassword));
form.add(new SubmitLink("submitLink"));
add(form);
This is just one example - we see elsewhere in the logs sometimes a
textfield that is setrequired(true) ends up nullpointering somewhere
when saving the object.
What could do this?
