Ramesh Reddy commented on OLINGO-811:
-------------------------------------
The real issue here is on client side the deserialization is done without
metadata first, so it does not know complex type from entity type, then it goes
though binding process to typecast that object. However, need to figure out a
way to not loose the count information during this process.
> Use of $count for expanded items does not work
