> Currently one has to use get() != null checks to see if a specific column has a value for any given row. But this involves the whole load and transfer stack to shift the data to the client just for it to drop the content. Better would be a server side check and only returning the boolean back to the client, especially if the checked cell is containing MB's of data.
