I upgraded to 15.2. After the update it is no longer allowing me to hide columns. I am getting the following console error:

Uncaught TypeError: Cannot read property 'key' of undefined

I attached my code below:

@(Html.Infragistics()
.Grid(Model)
.ID("CAMExpenseListGrid")
.AutoGenerateColumns(false)
.PrimaryKey("Id")
.RenderCheckboxes(true)
.AutoCommit(true)
.Columns(column =>
{

column.For(x => x.Id).HeaderText("Id").DataType("number");
column.For(x => x.ExternalId).HeaderText("ExternalId").DataType("text");
column.For(x => x.CAMName).HeaderText("Name").DataType("text");
column.For(x => x.YearlyCAMAmount).HeaderText("Amount/Yr").DataType("number");
column.For(x => x.MonthlyCAMAmount).HeaderText("Amount/Mo").DataType("number");
column.For(x => x.PerSqFtCAMAmount).HeaderText("Amount/SF").DataType("number");
column.For(x => x.StartingIncome).HeaderText("Starting Income").DataType("number");
column.For(x => x.IsCAMActive).HeaderText("Active?").DataType("bool");
column.For(x => x.CamStartDate).HeaderText("Start Date").DataType("date");
})
.Features(f =>
{
f.Paging().Type(OpType.Local).PageSize(20).TotalRecordsCount(Model.Count());

f.Responsive();

f.Updating()

cs.ColumnSetting().ColumnKey("Id").EditorType(ColumnEditorType.Numeric).Required(true).ReadOnly(true);

});

})
