Thanks for the pointers Tereza.
I think the cause of most of my problems was the existence of two
stacks with the same name, as you pointed out. After fixing that
issue, I now have this working fine.
Instead of passing in the name of the app stack, I found I could the
use "the long name of this stack", eg:
set the mainstack of stack "Structures" to the mainstack of the long
name of this stack
I also figured out what you recommended for the code to create the
