Hello Gerd,
I see, thank you. If $version=0 the latest submission is the specified
return value.
But the return value for $version=1 is always undefined. The first value
is given for $version=2, the seconed for $version=3, and so on.
This was the cause of my confusion and I wonder whether this is
intended. I am almost certain that this behavior differs from previous
LON-CAPA versions ...

I tried to demonstrate that it is possible to show all submissions:
submission( $partid, $responseid, $version )
If $version is 0, the latest submission is returned and for all other values
of $version the return value is undefined.
Have I made a mistake or this a bug?
Nope, this is how it *should* work.
However, if I remember correctly, this only works when the problem is already
inside a course, i.e., published and part of the table of contents of a course.
Did you try this inside a course, or has your testing thus far only been in
construction space?
- Gerd.
