Problem running Tapestry 5.8.2 with Hibernate 5.4.32.Final

[Christopher Dodunski (Tapestry)]

Hello,

I've encountered an issue after upgrading from Tapestry 5.6.4 to 5.7.3.  
This included moving from Hibernate 5.1.0.Final to 5.4.32.Final (as per 
the guidelines).

The HibernateCrudServiceDAO method below is now failing to fetch named 
queries via the injected org.hibernate.Session, resulting in a null 
pointer exception when attempting to write parameters to it.

I'm wondering whether this might have something to do with 
org.hibernate.Query having been deprecated and replaced with 
org.hibernate.query.Query.  I understand the tapestry-hibernate package 
was reworked around the time of Tapestry 5.7.3 to support changes in 
Hibernate.

Incidentally, the issue remains with Tapestry 5.8.2.

Any help/insights would be much appreciated.

Thanks & regards,

Chris.


import org.hibernate.query.Query;
import org.hibernate.Session;
...
    @Inject
    private Session session;
...
    public <T> T findUniqueWithNamedQuery(String queryName, Map<String, 
Object> params){
        Set<Entry<String, Object>> rawParameters = params.entrySet();
        Query query = session.getNamedQuery(queryName);

        if(query == null) LOG.error("Oops, Hibernate session returned 
null Query object!");
        if(query != null) LOG.debug("Query string = " + 
query.getQueryString());

        for(Entry<String, Object> entry : rawParameters){
            LOG.debug("Entry key = " + entry.getKey());
            LOG.debug("Entry value = " + entry.getValue().toString());
            query.setParameter(entry.getKey(), entry.getValue());
        }

        return (T) query.uniqueResult();
    }
