List Positions
Can some one explain what is happenign here so, straightforward position; [ alist = {1,3,2,"a",2,2,2,2,"a",2,2,2,2,"a",2,2} ,
result = List.PositionOf( alist, "a",Occurrence.All) ] but her...
There's guaranteed to be an error in the last member of the list (you're referring to x+1 which doesn't exist).
Using an otherwise = true will mask that error which is fine, although as a coder you'll realise this masks any other error that may appear in the list and you wouldn't be alerted to it. My approach would be to remove the known error at the end of the list with a List.RemoveLastN(tflist,1) (or do it in the same line) so that you're only removing the expected error, then do your ListPositionOf with Occurence.All.
