Ramesh Reddy commented on OLINGO-1009:
--------------------------------------
The cycle detection needs to be prevented only in the case where $levels = max
is presented, not when say $levels=5
>No, that is not correct.
Sorry Steve, I missed the text where cycle should be resolved with enityRef in
the spec, I fixed that now and updated the test case now. Give it a look
