问题 In hamcrest (1.3.RC2, with no JUnit dependencies) I am failing using iterableWithSize() with a SpringDataNeo4j library. I have an (extension of) an Iterator parameterized with Content like this EndResult<Content> contents = contentRepository.findAllByPropertyValue("title", "*"); where EndResult is package org.springframework.data.neo4j.conversion; public interface EndResult extends Iterable {...} and Content is a a @NodeEntity Pojo. With the help of Mark Peters I learned that I should call it

问题 In my Neo4j/SDN project I have to implement a following task - I have a parent Node(let's say ParentNode ) that must define a set of product characteristics, for example: weight: Double size: Integer license: String active: Boolean Also, new product characteristics( with any new name and type ) can be added during the application runtime.

问题 Since I updated from RC1 to RELEASE I get this exception: org.springframework.data.mapping.model.MappingException: No index name allowed on label based indexes which means @Index will now default to Label and not Simple indexing.
