Exception Deleting DataObject with to-many relationship

[Joe Baldwin]

I am getting an odd exception when I attempt to delete a DataObject with a 
"to-many" (aka child list).

Here is the pseudo code:

1. deleteObjects(parent.getChildList())
2. deleteObject(parent)
3. objectContext.commitChanges()

on Exception
        objectcontext.rollbackChanges()


It is very odd but I am getting the following error:

org.apache.cayenne.reflect.PropertyException: 
[v.3.0B1 Nov 03 2009 19:16:06]
Error unsetting to-many DataObject property: salesOrderList

But it is deleting all the associated database rows.

Am I missing a step in the delete procedure?

thanks,
Joe
