             Summary: Create Apache Isis API for custom Queries sent to the Objectstore by the PersistenceManager
                 Key: ISIS-422
                 URL: https://issues.apache.org/jira/browse/ISIS-422
             Project: Isis
          Issue Type: Bug
          Components: Core
    Affects Versions: core-1.2.0
            Reporter: Oscar Bou
            Assignee: Dan Haywood


Current API does not support the option to define custom queries as SQL strings that will be resolved by the current Objectstore.

Proposed patch by Dan:

Take a copy of IsisJdoSupport and IsisJdoSupportImpl.

In IsisJdoSupport, add:

PersistenceManager getJdoPersistenceManager();


In IsisJdoSupportImpl, add:

public PersistenceManager getJdoPersistenceManager() {
   return getObjectStore().getPersistenceManager();
}

protected DataNucleusObjectStore getObjectStore() {
   return (DataNucleusObjectStore)
getPersistenceSession().getObjectStore();
} 

Then register this as a service and inject into your repositories etc.

There's a plan for integrating Lucene into Isis. Then a lot
of these adhoc queries may just disappear as a requirement.
