Dynamics CRM : Incorrect drill-down record resolution on Virtual Entities

Hi,

I've configured an ODATA endpoint which I've succesfully coupled with D365CE through a Virtual Entity. The only particular thing about it is that it has a lookup relationship against contact. Now, the problem is, D365CE is unable to properly resolve drill down navigation from either subgrids or plain view results; It always renders up the same virtual entity record.

For instance, say I query through advanced find against my entity to any criteria wich returns record A with guid G1, record B with guidG2 and record C with guidG3. No matter on which of these records I click on, I always end up in detail form of "A".  

I've tested the Odata service with postman and it works perfectly, any filter I define is applied on the results. 

Any hints before raising a ticket to MS? :)
