I have a bunch of nested objects...so ...
Class can itself contain a list of Class objects to create a hierarchy...
Ok, so I do
Class class1 = new Class();
class1.Items.Add(new Class());
class1.Items.Add(new Class());
So "class1" contains two child class objects and those get persisted to the database.
Is there any way inside those two class objects to figure out what the parent object is?
Does that make sense?

Hi Steve,
there are two principal ways to store a collection with OpenAccess: with join table or with inverse reference.

The latter one is not able to maintain the list position, so the list is more like an unordered collection. But the big advantage is that using the inversely stored collection allows to use - the inverse reference. Please see http://www.telerik.com/help/openaccess-orm/mapping-properties-one-to-many-reference-without-join-table.html for more details.
