I have created a parent class which has a list of children (composition).

I manually create a parent and add a child using this code:

parent = Parent.NewParent();

child = parent.Children.AddNew();

parent.Save();

However when parent.UpdateChildren() is called the varible parent._childrenHydrated is false and therefore the new child is not added to the database.

I think that the solution is to add the dollowing line to parent.Dataportal_Create():

parent.Dataportal_Create()

{

...

_childrenHydrated = True;

}

This will ensure that any new children will be saved correctly.
