#SpringBind on dynamically created fields
I'm working on a small Spring MVC application and I'm trying to create a dynamic form using Velocity, Spring and jQuery.
I followed that article, of course with some changes :
http://eggsylife.co.uk/2009/11/30/sp...ists-and-ajax/
My Person class has a List of phones (it's a LazyList, with AutoPopulatingList it doesn't work)
Code:
....
@OneToMany(cascade = CascadeType.ALL, mappedBy = "person", fetch = FetchType.EAGER, targetEntity = Phone.class)
private List<Phone> phones;
public Person() {
phones = LazyList.decorate
(new ArrayList<Phone>(),
new InstantiateFactory(Phone.class));
}
....
My PersonFormController method
Code:
@RequestMapping(method = RequestMethod.GET)
public String showPersonForm(ModelMap modelMap) {
Person person = new Person();
modelMap.addAttribute(person);
return "personForm";
}
and in my personForm.vm file in one form there are :
1. Person adding #springBind
HTML Code:
<td>Name</td>
<td>
#springBind("person.name")
<input type="text" name="name" value="$!person.name">
<td width="60%">
<font color="red">$!{status.errorMessage}</font>
</td>
</td>
2.And Phone adding
HTML Code:
<table id="tablePhones">
<tr>
<td>Number</td>
<td>
#springBind("person.phones[0].number")
<input name="person.phones[0].number" size="40" />
</td>
<td><a href="#" id="add">Add new phone</a></td>
</tr>
</table>
I am able to produce new inputs for phone adding with AJAX and jQuery just like in an article posted above and it works fine.
So now when I fill all fields in my PersonFormController there is a method
Code:
@RequestMapping(method = RequestMethod.POST)
public String addPerson(@ModelAttribute("person") Person person,
BindingResult result) {
personValidator.validate(person, result);
if (result.hasErrors()) {
return "personForm";
} else {
personDao.saveOrUpdate(person);
return "redirect:index.htm";
}
}
Validation is fine and... only the Person is persisted and always one Phone with all null values. What do I need to change to fully persist all phones with current person? Could anyone help me with this? I am trying to figure it out for a long time..
Maybe You need more information or my code?
Thanks
