It would be more likely that the dataProvider length is still 0 until you get your first page. If that's not the case, can you make a small example?

The ArrayCollection represents the files in a directory and I am performing pagination. Before I populate the ArrayCollection with valid FileVO objects it is filled with null items for every file in the directory. I specify the nullItemRenderer property of the 'File Name' DataGridColumn so that a spinner animation will display until I update the ArrayCollection as the result of a paginated query to fetch the contents of the directory. When I first select a directory I never see my nullItemRenderers. It is not until the first page loads, updates the ArrayCollection with the first page of results and valid item renderers are created and displayed will I see the nullItemRenderers when scrolling the rest of the collection. It seems the nullItemRenderer is only used once the cache of ItemRenerers is full of valid Item renderers for all the visible rows in the DataGrid. How can I have the DataGrid use nullItemRenderers even before a non null item has been rendered? Any help is greatly appreciated. Thanks, Greg
