> 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?
