Michael Bolz commented on OLINGO-811:
-------------------------------------
Hi [~riccardomariani],
Thanks for the suggested solution.
Based on this I created the branch
[OLINGO-811_CountForExpand|https://git1-us-west.apache.org/repos/asf?p=olingo-odata4.git;a=shortlog;h=refs/heads/OLINGO-811_CountForExpand]
and commited a first version.
I have to admit, that in this *first version* not all tests are running
(problem with XML in *client* and *fit* test).
However, the core and JSON parts as basis for a solution discussion works.
Can you please take a look into and give feedback.
Best Regards,
Michael
