Dag H. Wanvik commented on DERBY-5933:
--------------------------------------
Thanks for looking at the test and the further comments, Knut. You are right,
the extra test for JoinNode made the fix so ugly I called it a hack ;-)
I have the same problem with the code as you do as far as understanding the
conditions under which the VCN has a columnDescriptor.
I'll see if i can run some tracing over the set of regressions tests to see if
I can understand it a little better.
Committed the patch d5933-remap+test as svn 1390205.

> Hello
> I have a simple database with 100 records.
> I am running a SQL query from Netbeans GUI though JDBC
> This query was generated by Hibernate ORM.
> In certain circumstances the result rowset is not sorting.
> When I use condition morefld2_.mf_id in (5) the result is unsortable.
