Kevin,
In 1.3 beta the discription of the AutoDeleteOnParentDeleted property is applied to the AutoCancelOnParentCancel property

///

/// Specifies if this object's Cancel method is automatically called when
/// its parent business object raises the Canceled state change event.
///

[Description("Specifies if this object's Delete method is automatically called " +
"when its parent business object raises the Deleted state change event."),
Category("Data"),
DefaultValue(false)]
public virtual bool AutoCancelOnParentCancel

Thanks,
Max...
