To solve a problem I have the following line in an org file:
- [ ] B (org-list-set-checkbox (line-beginning-position)
(org-list-struct) "[X]") ITEM STRUCT CHECKBOX (org-list-send-item
(line-beginning-position) 'end (org-list-struct)) ITEM DEST STRUCT
Executing the org-list-send-item brings the entry to the end of the list,
but executing org-list-set-checkbox does nothing. What am I doing wrong?
Because looking at the API I use the right parameters. I also do not get an
error message.

You would have to apply the new structure to the buffer with `org-list-write-struct'. Anyway, it's much simpler to use `org-toggle-checkbox'.

See `org-list-write-struct' docstring. Basically, STRUCT doesn't match real structure anymore since step C. You need to provide the original structure as a third argument so `org-list-write-struct' can modify buffer by set difference.

But one thing I do not understand. When you do an org-list-write-struct, you want to change the structure.

IIRC, it's just syntactic sugar since `org-list-write-struct' will do the `copy-tree' for you in most situations (i.e., when you don't use a function that modifies structure by side-effect).
