Hi Ed, First of all, nice work. You are implementing a hard thing to do, moving between pages and restoring data for forms. Another approach which might work would be using modals, as you can have them in the DOM outside the form.
I agree with Kevin that debugging the contents of this_parent and this_parent.country_make should help. You will probably find that "country_make" is nil. I suggest you look at the Ajax request that happens in the first select: - Is the parameter sent to the correct place? - Does the controller do its job correctly? (receive the parameters, instantiate a new object with them) - How does the JS response look like?
