Bug? Use PersistSelection with GroupPaging

[Nils]

Hi everyone,

not sure if I found a bug or if i'm just doing it wrong.

What I try is to create a grid that is per default grouped with GroupPaging and has a checkbox selection column with PersistSelection.

However I only get a js error "Cannot read property 'undefined' of undefined" @init._restoreSelection (kendo.all.min.js:62).

I tried adding an Id field but it still doesn't work. Only changed error to "Cannot read property 'Id' of undefined".

If I remove the PersistSelection it works fine.

Html.Kendo().Grid<MyViewModel>()
                   .Name("myGrid")
                   .Columns(c =>
                   {
                       c.Select().Width(50);
                       c.Bound(x => x.Id).Hidden();
                       c.Bound(x => x.ArticleNo);
                       c.Bound(x => x.ArticleGroup).ClientGroupHeaderTemplate("<input class=\"k-checkbox groupSelect\" type=\"checkbox\"> #= value  #").Hidden();
                   })
                   .PersistSelection()
                   .ToolBar(t => t.Search().Text(Localizer.Lang_SearchInTable))
                   .Events(x => x.DataBound("eventMyGridDataBound"))
                   .DataSource(dataSource => dataSource
                                   .Ajax()
                                   .PageSize(50)
                                   .GroupPaging(true)
                                   .Group(x => x.Add(y => y.ArticleGroup))
                                   .Read("GridRead", "Article")
                                   .Model(m =>
                                   {
                                       m.Id(f => f.Id);
                                       m.Field(f => f.ArticleNo);
                                       m.Field(f => f.ArticleGroup);
                                   }))
