I've been playing with MVC 3 in a test project and have the following issue.
I have Group & Subscriber entities and those are coupled through a SubscriberGroup table.
Using the DetailView of Group I open a
view of SubscriberGroup containing all subscribers.
This list has the option to filter.
So far it all works, however when I call the AddToGroup method on the controller it fails. Specifically it goes into the method but doesn't pass the subscriberCheckedModels list.
Am I doing something wrong?
View: SubscriberGroup Index.aspx
<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.master" Inherits="System.Web.Mvc.ViewPage<Mail.Models.SubscriberCheckedListViewModel>" %>

<h2 class="common-box-title">

<p>
<% using (Html.BeginForm("Index", "SubscriberGroup"))
{ %>
<input name="filter" id="filter" type="text" />
<input type="submit" value="Search" />

Model,FormMethod.Get, null))
