Hi all,
I'm new to Wicket.
I'm building an application, actually finished most of the businness model
classes.
My businness classes don't have a default constructor, they have a
constructor with parameters. Inside the constructor, it calls to the
setters. These have the business rules implemented.
For example:
public User(String email, String name,
String password, Date birth) throws BusinessException {
setEmail(email);
setName(name);
setPassword(password);
setBirth(birth);
}
public void setEmail(String email) throws BusinessException {
testSetEmail(email);
doSetEmail(email);
}
private void testSetEmail(String email) throws BusinessException {
// Check the format and if it is wrong throw a BusinessException
}
private void doSetEmail(String email) {
this.email = email;
}
Now, this is a trivial example, I have much more complex ones.
What I want to know is how should I use this kind of classes with Wicket.
I clearly cannot use the User object and a CompoundPropertyModel because I
don't have a default constructor.
So, should I use a UserDTO and a CompoundPropertyModel and have the
textfields in a form binded to it ? and then after the form is submitted
obtain the properties from the DTO and create the real User object? Of
course, I should try/catch the call to the constructor and if any exception
is thrown show that to the user in a feedback panel.
What do you think?
Thanks.
