I’ve always thought that an operator like “a list of…” might be handy. In this case a list of integers, so you could check to see if the list you want to sort is a valid list of integers.

If you were to change the bug report to sort on the field itself, then the sort is performed but the answer does not execute. If you clicked the button again, then the answer does show. If you revert to the saved stack and add a valid value after the bad one, the answer works as expected with the bad value being first.

To be clear: the above is NOT what I'm seeing. Mark W says in the bug report: The 'sort ... by ...' command has always allowed the by expression to be fault tolerant - if evaluating it generates a runtime error then the sort key for that element is just taken to be the original element. And that is what I'm seeing. For example, this code does not exit -- it displays the answer dialog as if nothing out of the ordinary has happened: on mouseUp sort lines of fld 1 numeric by sortVal(each) answer "done" end mouseUp function sortVal S return item 2 of S + item 3 of S end sortVal It seems to be sorting as Mark described: when the function fails, the whole line is used for the sort. And that "fallback to the whole value needs better documentation, and could lead to some truly dismal debugging situations, but it doesn't seem like a bug to me. The original report, if I were able to replicate it, would clearly be a bug. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
