I have a Run class with list of strings:

public interface Run extends EObject
{

...

/**
* @model
* @return
*/
public EList<String> getMessages();
}

My ecore model is here http://bernshtam.name/temp/vm.ecore

I make following query:
Query q = _session.createQuery("from Run as run where
run.status = ? and ? in elements(run.messages)");
q.setMaxResults(200);
q.setFirstResult(100);
q.setInteger(0, status);
q.setString(1, string);
List<Run> runs = q.list();

and receive exception:
Nov 5, 2008 2:51:14 PM org.eclipse.emf.teneo.TeneoException <init>
SEVERE: Exception when setting eContainerFeatureID for:
com.cadence.pavel.vm.impl.RunImpl to value: null

What I'm doing wrong?

Thank you

Hi Pavel,
It seems that the container of the Run object has not been set in the db. I will try this out a
little later today and let you know what I found.

Hi Pavel,
I tested this (also with your query) and with me it works fine.

I think the following happened. In your first model you did not have the containment set. So the
database and the records were created without the econtainer columns. Then when you changed your
model the econtainer columns were created. For existing records the value of the new columns is set
to null. As the econtainterfeatureid is a primitive field it can not handle null values. I will
repair this in a new build (in a few days) so the behavior will be more robust.

In the meantime if you recreate the database then this should go away.
Let me know if you still have issues.
