Hi,
perhaps to keep it simple (or at least on the same level of complexity as
current solution has) we can use
{code}
...
FROM SalesOrderHeader e1
JOIN e1.salesOrderItem e2
WHERE e2.delivered = true
...
{code}
for all types of relationships (*ToOne and *ToMany)?
I.e. if filter contains navigation, then (a) use join context and (b) for each
such filter item generate JOIN.
Best regards,
Alex

> 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?
