What is the binding order when a form is submitted? I came across an example
in the Stripes book (which is a very nice read) that had a form with a
hidden field that contained the object that was being edited. When the form
is submitted for update the action bean form checks to see if the id is
null, if it's not it reads it from the database and uses that model object
to back the form.
ActionBean
---------------------------------
private Integer contactId;
public Integer getContactId() {
return contactId;
}
public void setContactId(Integer id) {
contactId = id;
}
public Contact getContact() {
if (contactId != null) {
return contactDao.read(contactId);
}
return contact;
}
Is there any guarantee that the hidden form value (contactId) would be set
on the ActionBean before getContact is called? Is it the form order that
determines this? I have no idea.
Thanks
