Yes, no other possibility than NPE

java.lang.NullPointerException
at org.hibernate.ogm.type.impl.ManyToOneType.getIdGridType(ManyToOneType.java:56)
at org.hibernate.ogm.type.impl.ManyToOneType.nullSafeSet(ManyToOneType.java:64)
at org.hibernate.ogm.query.parsing.impl.ParserPropertyHelper.convertToBackendType(ParserPropertyHelper.java:66)

Still there is 5.0

While I was trying to compare entities I got NPE.

FIY I tryied to find out why and it was because in:
Neo4jDialect.getNamedParameterValuesConvertedByGridType()
is called
gridType.nullSafeSet with last parameter (session) null
and in
ManyToOneType.getIdGridType()
is called a method on the session resulting in NPE.

Would be a nice to have in 4.2

"select c from Customer c where c.country = :country"

query.setParameter("country", country);

, Can you add an example for a query you'd like to see supported?
