Hi all,
I have been using D2W and have been managing quite well without
having to write any code. However, I have run into a situation
where I need to insert a bunch of objects when another object is
being created. I was wondering if I could write this code in the
validateForSave of the original object.
In a word, no. That is not a safe thing to do.

For example, if I need to save a few Bar objects when I create a
Foo, can I write the code for the creating of the Bar objects in
the validateForSave of the Foo class? Well, I know I can. But I was
wondering if this was a good way of doing this. Or is there a
better way to achieve this without having to write my own component
etc.
Use awakeFromInsertion.
