Let me start by saying that I am totally new to JCR and ModeShape. I am just playing around a little. And I got a weird error.

The statements:

Query q = ses.getWorkspace().getQueryManager().createQuery("SELECT author,time,title,body FROM [nt:unstructured] WHERE author = '" + author + "' AND title IS NOT NULL", Query.JCR_SQL2);

QueryResult q1 = q.execute();

gives me this error:

Exception in thread "main" org.modeshape.jcr.query.parse.InvalidQueryException: The view references a non-existant column 'mode:localName' in '__ALLNODES__'

And I am totally blank about what can cause this error.
