-------------------------------------

Hi [~jpenninkhof],

The Thanks are certainly welcome by all of the contributers to this issue   ;o)

The failing unit test is a minor issue of [OLINGO1014|https://issues.apache.org/jira/browse/OLINGO-1014]
and do not affect this issue here.

Best Regards, Michael

> We are receiving an error when we try to filter on a navigation property.  In our solution
we have a Notification entity and a User entity, we would like to retrieve a specific Notification
but only if it is linked to the requesting user.  This would involve an ODATA request which
filters on both the UserId and the NotificationId.  An example of the URL we are invoking
is:
> dspplatform.svc/Notifications?$filter=NotificationId%20eq%204%20and%20UserDetails/UserId%20eq%202
> This returns the following error:
> org.apache.olingo.odata2.core.edm.provider.EdmNavigationPropertyImplProv cannot be cast
to org.apache.olingo.odata2.api.edm.EdmProperty
> Can you please advise on how to perform filters on a Navigation property as we need this
as part of our core functionality?
