Cannot set initial values from viewmodel

[Mac P]

Hello,

When i bind the Multiselect list to ViewBag the list renders fine. However the "Values" property never gets set. I have tried with IEnumerable object as well as list<string> or string[] of ids. I cannot find any help online. When i post the viewmodel does post selected values. 
I have also played with Autobind true and false

Here is the code

@{
                       Html.Kendo().MultiSelectFor(model => model.ActivityIds)
                           .BindTo(new SelectList(ViewBag.Activity, "ActivityId", "ActivityName"))
                           .Value(new SelectList(ViewBag.SelectedActivites, "ActivityId", "ActivityName"))

                           .Placeholder("Select Activity ..")
                           .HtmlAttributes(new { style = "width: 800px;" })
                           .Render();
                   }

ViewBag.Activity = db.GetActivityList(Constants.APP_SC).ToList();
            if(smallCellViewModel.HasValue() && smallCellViewModel.ActivityIds.HasValue())
            {
                ViewBag.SelectedActivites = db.GetActivityList(Constants.APP_SC).Where(c=>smallCellViewModel.ActivityIds.
                    Contains(c.ActivityId)).ToList();
            }

Hi Mac,

I tried to reproduce the issue locally, but everything worked as expected. Could you please check this screencast and let me know if using this approach works for you? Also, can you confirm that the query returns any items and the SelectedActivites is populated?
