Hello Arya,
I am not sure I am fully understood your use case. Do you have navigation between 2 entity sets or no?
if yes, please verify that they are working.
Basically, URL parameters are parameters that added to URL after the "?" mark sign and they are not replacing the standard ODATA navigation mechanism.
In standard master detail template the navigation between master to details is with hash parameters, for example:
#&/detail/SalesOrders('SalesOrderNumber%202')
Thanks Alex
