Fixes 362

[tywalch]

This branch fixes issue #362. The root cause of the issue was that one of the composite attributes was hidden. Because the cursor was created using the "formatted" return item, it was the hidden composite was not available to the cursor formatting function. We now check for this unique case and perform some additional calculations. Ideally this reduces the surface area of performance implications to only entities that have a hidden composite attribute defined.
