How to send list of Objects to View and back to Post method in controller
java, post, spring-mvc
Solution
I think this link will help you set up what you are trying to do:

It looks like in your form you need to modify it to something like:
<form:form method="post" action="savePerson" modelAttribute="persons">
<c:forEach var="person" items="${persons}" varStatus="status">
<form:input path="person[${status.index}].FName" name="FName" id="FName" value="" />
<form:input path="person[${status.index}].LName" name="LName" id="LName" value="" />
</c:forEach>
This SO question has a pretty good example that might help you out too: List<Foo> as form backing object using spring 3 mvc, correct syntax?
Problem
Suppose I have class `Person`, I made a list of `Person` instances and add this list to a `Model`. ``` List<Person> persons = new ArrayList<Person>(); model.addAttribute("persons",persons); return "savePersons"; ``` In the `View` page I have a form: ``` <form:form method="post" action="savePerson" modelAttribute="persons"> <c:forEach var="person" items="${persons}"> <form:input path="person.FName" name="FName" id="FName" value="" /> <form:input path="person.LName" name="LName" id="LName" value="" /> </c:forEach> <button type="submit"></button> </form:form> ``` When I click on the submit button I want to bind the `Person List` to the POST method on the controller.. ``` @RequestMapping(value = { "savePerson" }, method = RequestMethod.POST) public String savePerson(Model model, HttpServletRequest request, HttpSession session,@ModelAttribute("persons")List<Person> persons) { System.out.println(persons.length); return "success"; } ``` but the `persons` list is not binding/fetching at the `POST` method. Is it possible to bind a list objects in this way or is there an alternative for this?
