not have a CQLMappedEntityValueConverter on List valueConverters.

[rjesususa]

not have a CQLMappedEntityValueConverter on list valueConverters of QueryBuilder.class after initialize application on first execution of query.

then my query return a NULL object, but I have expected a entity.

in second call of query, the class CQLMappedEntityValueConverter is present in list valueConverters, returning my object correctly.

Can you provide code and how you are initializing the factory?

the follow code initializing the factory:

                persistenceFactory = new HectorPersistenceFactory();
                persistenceFactory.setAutoDiscoverHosts(true);
                persistenceFactory.setDefaultConsistencyLevel(ConsistencyLevel.ALL);
                persistenceFactory.setEntities(entities);
                persistenceFactory.setClusterName(getProperties().getProperty("clusterName"));
                persistenceFactory.setDefaultKeySpace(getProperties().getProperty("defaultKeySpace"));
                persistenceFactory.setContactNodes(new String[]{ getProperties().getProperty("contactNodes")});
                persistenceFactory.setThriftPort(Integer.parseInt(getProperties().getProperty("rpcPort")));
                persistenceFactory.setPoolName(getProperties().getProperty("poolName"));
                persistenceFactory.setDebug(Boolean.parseBoolean(getProperties().getProperty("debug")));

                persistenceFactory.init();

Query query = Query.get(QueryBuilder.select(QueryBuilder.allColumns(), QueryBuilder.from(entity.getClass()), QueryBuilder.where( QueryBuilder.eq("project", project) )));

project is a column family mapped in my class.

[rjesususa]

the atribute "entities" is a list of class

[rjesususa]

any atualization?

[raulraja]

Can you also send the Entity including all mappings?

public String getId()

public void setId(String id)
{

}

in my query i use segmento in clausule where.

Query query = Query.get(QueryBuilder.select(QueryBuilder.allColumns(), QueryBuilder.from(Empresa.class), QueryBuilder.where( QueryBuilder.eq("segmento", segmento) )));

entity segmento is:

public class SegmentoProjeto extends EntityBase
{

private static final long serialVersionUID = -8185147223966996268L;

@Key
private String key;

@Column(indexed = true)
private String nomeSegmento;


/**

 */
public String getKey()
{
    return key;
}

/**
 * @param key the key to set
 */
public void setKey(String key)
{
    this.key = key;
}

/**
 * @return the nomeSegmento
 */
public String getNomeSegmento()
{
    return nomeSegmento;
}

/**
 * @param nomeSegmento the nomeSegmento to set
 */
public void setNomeSegmento(String nomeSegmento)
{
    this.nomeSegmento = nomeSegmento;
}

public String getId()
{
    return key;
}

public void setId(String id)
{
    key = id;

}

What is the code that you are using to pass the query to the factory and retrieve the List of objects?

[rjesususa]

Query query = Query.get(QueryBuilder.select(QueryBuilder.allColumns(), QueryBuilder.from(Empresa.class), QueryBuilder.where( QueryBuilder.eq("segmento", segmento) )));

response = getPersistenceFactory().getSingleResult(Empresa.class, query);

[rjesususa]

is important execute this query on first time after startup server application.
