Your first method creates a reference to the form scope, but does not store the data for that reference in separate memory space. That's why the structure is blank in the second page- the form scope has changed, and your session variable is still just a reference to form scope.
In the second example, you are creating a separate copy of the form data in its own memory space (and NOT a reference to the form scope), so changing the form scope does not affect it. > Since complex data structures are passed by reference, I > figured that since I had a persistent reference to the current form > structure it would exist on the next page.
