hi,

I have been looking into using the JDO LifecycleListener and
InstanceCallback features. (<http://www.datanucleus.org/products/
accessplatform_1_1/jdo/lifecycle_listeners.html>, <http://
www.datanucleus.org/products/accessplatform_1_1/jdo/instance_callbacks.html>)

I've run into something that seems like it might be a bug in the App
Engine implementation of these features.

Specifically, 'load' events (those events consumed by
LoadLifecycleListener and LoadCallback) only seem to be generated when
an object is loaded via getObjectById, but are *not* generated when
the object is loaded via a query.

Is this the intended behaviour?  If so, does anyone know the rationale
behind it? Why would we not want load events triggered for objects
returned by query as well? (I have no basis of comparison with other
JDO implementations).
