Hi Olivier, It's so interesting when someone follows up on a post from a year and a half ago.
I haven't used this code in v16 yet. But in general what I've found most reliable when fiddling with dynamic variables and listboxes is to let 4D tell you what it did by using the LISTBOX GET ARRAYS command. For example, if I add some arrays immediately after I'll call LISTBOX GET ARRAYS and use the array of pointers to the column variables. For whatever reason, and there are arguments to be had about why I shouldn't have to do this, I can't recall it not working. Same with the footer vars - go ahead and pass a nil pointer (easily derived by putting C_POINTER($nil) in your method) then use the pointer returned by 4D in LISTBOX GET ARRAYS. Like I said, 'yes, you should be able to pass a pointer and then use that pointer.' Sometimes yes, sometimes no. I don't really care - I just get the pointer arrays and it always works. I do this so much I found it handy to make a method that takes a listbox name and returns a specified array (colVars, footerVars, headerVars, etc.) so I don't have the overhead of directly calling LISTBOX GET ARRAYS.
