 David K. Watson - Order on show past answers pages  3/1/2006; 3:44:53 PM (reads: 400, responses: 2) We have come up on an irritating behavior on the page you get when you click on the "show past answers" button on a problem page. This behavior only happens if the problem has a large number of answers. As an example, there is a linear algebra problem that has 18 answer blanks to fill in, and if the order for the answers is #1, #2, ... ,#18 as they appear in the problem, the answers appear on the "show past answers" page in the order #1, #10, #11, #12, ..., #18, then #2, #3, ... , #9, i.e., you see the first answer, then the second half of correct answers in order, followed by the rest of first half of correct answers in order. My interpretation is that there is some code that is intended to wrap the display in two rows as #1, #2, #3, ... , #9, #10, #11, #12, ..., #18, but instead this somehow got flattened into one row with the intended second row after the first entry. This makes it very difficult to check on a student's past answers to see how they have gone wrong. Has this been fixed in a recent version of webwork? We are using some point release of 2.1. <| Post or View Comments |>

If you want to edit two lines in one file, the bug fix is easy. In the file .../webwork2/lib/WeBWorK/ContentGenerator/Problem.pm edit the following two lines: line 35: append "sortByName" to the qw list. If you have the lastest version this meansreplacinguse WeBWorK::Utils qw(readFile writeLog writeCourseLog encodeAnswers decodeAnswers ref2string makeTempDirectory path_is_subdir);byuse WeBWorK::Utils qw(readFile writeLog writeCourseLog encodeAnswers decodeAnswers ref2string makeTempDirectory path_is_subdir sortByName);but if your qw list if different from the above, just add "sortByName" to the end.line 937replace foreach (sort keys %answerHash) {by foreach (sortByName(undef, keys %answerHash)) { <| Post or View Comments |>
