Grails + Mongodb + Spock: NullPointerException being thrown when doing embedded field query

问题

On one service I'm trying to do something like:

Organization.withCriteria {
            eq( "active", true )
            eq( "location.region", region)
        }

which is working but when calling the method inside a unit test I get:

java.lang.NullPointerException
    at org.grails.datastore.mapping.keyvalue.mapping.config.KeyValuePersistentEntity.getPropertyByName(KeyValuePersistentEntity.java:75)
    at grails.gorm.CriteriaBuilder.validatePropertyName(CriteriaBuilder.java:954)

回答1:

Should be:

Organization.withCriteria {
        eq( "active", true )
        location {
           eq( "region", region)
        }

    }
