I'm currently struggling with the MultiSelect inside a Grid Editor Template in that the posted model has too many strings.

This is from my editor template...

@(Html.Kendo().MultiSelectFor(model => model.messages)
      .Name("key_messages") // With or without makes no difference
      .Placeholder("Select Key Messages")
      .BindTo((System.String[])ViewData["key_messages"]))

My string array, "key_messages" is defined in my controller

string[] key_messages = { "work ethic", "efficiency", "fiscal" };
ViewData["messages"] = key_messages;

In my model

public string[] key_messages { get; set; } //I've also tried using List<string> with same results

Using fiddler, I can see that the posted data contains way too many objects.  For example, if I select "work ethic" and "efficiency", I get the following.

key_messages[0]
key_messages[1] work ethic
key_messages[2] work ethic
key_messages[3] efficiency

To make matters worse, if I save this, then attempt to remove one of the "work ethics", I get this (even though only two selections remain)...

key_messages[0]
key_messages[1] work ethic
key_messages[2] work ethic
key_messages[3] efficiency
key_messages[4] work ethic
key_messages[5] efficiency

I'm assuming that this is some type of serialization problems but I've not been able to put my finger on the problem.  

Please help.

Hi Ben,

This is a strange problem. There is a slight chance that this could be related to this bug report. Could you review it and let me know if this is the case? If it isn't, would it be possible to send us more details about your current implementation that will help to replicate the problem locally? A runnable test project will be of a great help.
