Subject [jira] [Commented] (OLINGO-1146) CLONE - Cannot Filter on Navigation Property

Michael Jung commented on OLINGO-1146:
--------------------------------------

I was obviously blind, I just saw it as an open head and thought it would not be included
yet. Reading this issue more carefully would have certainly helped - thanks anyways for pointing
it out.

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?
