#39169 — JCR ModeShape non-existant column 'mode:localName'

I am playing a little bit with JCR.

I have this piece of code doing a JCR SQL2 query:

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();

When using JackRabbit as implementation it works.

When using ModeShape as implementation then execute gives me:

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

I tried both version 5.4.1 and 4.6.2 - same exception in both.

It is documented that ModeShape use a pseudo property/column
mode:localName.

https://docs.jboss.org/author/display/MODE50/Query+and+search

<quote>
ModeShape adds support for several columns that don't really exist on 
any node types but that are implicit in JCR. You can use these columns 
anywhere in a query that columns can normally be used.
...
mode:localName 	The local name of the node. The value is equivalent to 
jcr:name except without the namespace portion of the name.
</quote>

So it is supposed to be there.

But per exception message it is not.

And furthermore I am not trying to use it (explicitly).

Anybody with ModeShape experience that can provide some
hints about what I am doing wrong?

Problem went away when I stopped using namespace in
node names.

What can I say.
