Hi I am getting following error while saving NodeEntity object by using Neo4jTemplate

Cannot perform data updates in a transaction that has performed schema updates

Spring-data :- 

        <groupId>org.springframework.data</groupId>

public void addRepository(Repository repository) {
    template.save(repository);
}

SDN 3.0.0 needs now to have base-package configured in your Spring configuration.
Indeed, this is now needed since Neo4j 2.0.X doesn't allow insertion of index (schema change involved by your first save operation) in the same transaction as a data update (save of your entity in your case).

So if you use XML configuration for Spring, it would looks like: 

<neo4j:config graphDatabaseService="graphDatabaseService" base-package="com.myApp.myDomainPackage" />

where com.myApp.myDomainPackage contains all the node entities. instead of simple:

<neo4j:config graphDatabaseService="graphDatabaseService"/>

Data updates and schema changes need to happen in separate transactions. If they would be allowed in the same transaction various sorts of weirdness would be possible.
