LeBlender Umbraco Exception - An item with the same key has already been added about leblender HOT 4 OPEN

Yes, we have the same issue, will try to fix it and send a pull requests.

our code that breaks is:

@inherits UmbracoViewPage<Lecoati.LeBlender.Extension.Models.LeBlenderModel​>

@{
    var currentPage = Lecoati.LeBlender.Extension.Helper.GetCurrentContent();

    foreach (var child in currentPage.Children.Where(c => !c.GetPropertyValue<bool>("umbracoNaviHide")))
     {
         @Html.GetGridHtml(child, "layoutGrid")
     }
}

Looking into this it seems te be caused by this line:

if you remove the 'this.ViewData' from the creation of the new ViewDataDictionary things work.
It might be that I am overlooking something though that will now break?

So basically this commit should be reverted: 3516de3

This revert causes problems for me because properties I add to ViewData from my _ViewStart file are now lost. This needs to go back to the drawing board for a better fix.
