NullPointerException at Neo4jTemplate.findAll [DATAGRAPH-134] #681

Closed spring-projects-issues closed 12 years ago

spring-projects-issues commented 12 years ago

Hendy Irawan opened DATAGRAPH-134 and commented

I initialize with:

logger.info("Starting Neo4j");
String dir = "/together/project/SatukanCinta/satukancinta-neo4j-db_dev";
graphDatabaseService = new EmbeddedGraphDatabase(dir);
DelegatingGraphDatabase graphDatabase = new DelegatingGraphDatabase(graphDatabaseService);
graphTemplate = new Neo4jTemplate(graphDatabase);

Here's my Skill entity:

package com.satukancinta.domain;

import java.util.Set;

import org.neo4j.graphdb.Direction;
import org.springframework.data.neo4j.annotation.Indexed;
import org.springframework.data.neo4j.annotation.NodeEntity;
import org.springframework.data.neo4j.annotation.RelatedTo;

@NodeEntity
public class Skill {

    @Indexed
    private String name;

    @RelatedTo(type="TELLS", direction=Direction.INCOMING)
    Set<User> tellers;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

I get the list of all nodes by:

public List<Skill> getSkills() {
     ArrayList<Skill> skills = Lists.newArrayList(neo4j.findAll(Skill.class));
     return skills;
}

Access it from JSF View :

<h:dataTable value="#{skillsView.skills}" var="skill">
         <h:column>
                  <f:facet name="header">Name</f:facet>
                  #{skill.name}
         </h:column>
</h:dataTable>

But I get Error:

21:51:18,710 SEVERE [javax.enterprise.resource.webcontainer.jsf.application] (http--127.0.0.1-8080-1) Error Rendering View[/skills.xhtml]: javax.el.ELException: /skills.xhtml @20,60 value="#{skillsView.skills}": java.lang.NullPointerException
