psPlaceholder in a cWebGrid simply does not work.

In WebOrder, Orders View, Details Grid, add the line:
        Object oDetailGrid is a cWebGrid
            Set Server to oOrderDetailDataDictionary
            Set psPlaceHolder to "No Items to Show"
            Set piOrdering to 1
            Set pbFillHeight to True
            Set piColumnSpan to 10
            Set piMinHeight to 200
            Object oInventoryItem_ID is a cWebColumn
                Entry_Item Inventory.Item_ID
                Set psCaption to "Item ID"
                Set piWidth to 130
And see on a blank screen or an order with no items.

Works OK if you change it to a cWebList.
