I think you will need to get the list from ListDataProvider, remove
the item, and set ListDataProvider with the new list.  I believe it
should update automatically from there.  I think they suggest doing
rowcount and visible range.

The problem I have is that I am deleting a blob from the blobstore, not just removing it from the table, so once the RPC call returns it seems the best way is to reload the presenter using History.fireCurrentHistoryState() which makes the app query the DS again, and fill the table from scratch. It's only me that will be using this delete function, users will just be able to download so it's not a major problem in terms of efficiency.

I'm having a weird problem though - sometimes the RPC call returns successful after a delete and then when I reload the presenter it still gets the list including the file I just deleted. A refresh always sorts it out though - maybe a memcache problem or something? I am using Objectify so not sure if that may affect it.
