'Evening

I'm not used to working with ModelsBuilder, but with Umb8 i'm trying to get stuff to work.. Only running into a minor issue.

I believe I used to check if a treepicker had any values like this:

@if(Models.treePickerExample.Any())
{
   foreach(var item in Models.treePickerExample){
       doStuff();
   }
}

Or like this @if(Models.treePickerExample.Count() > 0) { foreach(var item in Models.treePickerExample){ doStuff(); } }

But currently this doens't seem to work, it both passed the check and goes to the foreach, but it breaks when there aren't any items selected.. Am I missing something?

I've got it working, but it feels like it's not the best method:

@if (Model.HasValue("treePickerExample"))
    {
        foreach (var item in Model.treePickerExample)
        {
            doStuff();
        }
    }

Or is this the correct way currently? There seems to be a bit of lack of documentation ;-)
