Why do you need to "go" to a card? Data can be accessed from any object, even
those that aren't "opened".
Yep, I 'need' to use 'go' only to avoid rewriting a lot of code. The app does
a bunch of functionality, guided by 'scripts' (not LC scripts); most of my
(handful) of clients use it interactively, with a GUI (some use it from the
command line as a scheduled task as well, but this has to date always been on
machines running Windows, that have a GUI even if nobody can see it). This is
the first case where we want to deploy it as a scheduled task on machine
without a GUI. It's not worth that level of rewriting to make it work - for
this particular case I could by now have coded an alternative in Python -
especially since much of the value of this is that all the functionality of
the app should be available.
So I don't 'need' to use go - but I want to!

Surely the point is that all those operations should be - and AFAICT most are
- implemented with suitable checks to make sure there is a UI; and that the
assertion is revealing one which hasn't been. I just wondered if anyone else
had come across this before and found out which operation it is that has this
problem.
