Hello All,
For some reason my students are unable to view the
answers to problem sets even after the due date and answers
available dates have passed. As the instructor with 'professor'
level permissions I have no problem doing so.
The generated hardcopy only shows the original problems.
I've already looked over the pertinent "Course Configurations"
fields, and find nothing that prevents them form generating
corrected solutions.
Any help would be appreciated!
Thanks, Hans

Re: allowing students to generate hardcopy with solutions

Hi Hans,
What version of/when did you install WeBWorK? There was a bug fix that got put into the CVS for showing answers in Hardcopy sometime at the beginning of August. A good first check would probably be to update your version of Hardcopy.pm (in ../webwork2/lib/WeBWorK/ContentGenerator) or your WeBWorK installation. That may take care of the problem.
This may work if you're on rel-2-4-patches; if you're running another WeBWorK version it may be necessary to try something else (e.g., just grabbing the Hardcopy.pm file from http://cvs.webwork.rochester.edu/viewcvs.cgi/*checkout*/webwork2/lib/WeBWorK/ContentGenerator/Hardcopy.pm?rev=1.94.2.2.2.3
and trying that in place of your existing version).

Hi Miao,
I'm going to apologize in advance for asking this, but did you restart apache after updating the module?
Thanks,

seems that Hardcopy.pm does not work for us.

cvs update: conflicts found in Hardcopy.pm
C Hardcopy.pm
The C indicates a conflict in the file between a local modification and changes made in the file located in the CVS repository. If you edit the file Hardcopy.pm you will see lines that look like:
<<<<<<<<<<<<<<<
code modifications that you mad
=========================
code modifications made in the CVS repository
>>>>>>>>>>>>>>>>>>>>>>>>>
You need to edit these by hand, selecting either the local modifications or
those from the CVS repository (but not both).
If you don't want to keep any of your local modifications you can also delete
the file Hardcopy.pm and then do
cvs update
to get the newest version.
The presence of lines containing <<<<<<<<<< are what are causing the
compile errors that you experienced.

Re: allowing students to generate hardcopy with solutions
by Hal Sadofsky -We've been having this problem too.
After searching the archives and following Gavin's suggestion to update Hardcopy.pm yesterday (replacing 1.94.2.2.2.1 with 1.94.2.2.2.3) we still had the problem. After I read the rest of the thread this morning and restarted Apache, the problem seems to have gone away.
So thanks Gavin, both for making the initial suggestion and for giving a kick to those of us who need to be reminded to do the obvious!

Hi, Gavin,
The Hardcopy.pm linked in your post works. Thank you.
I think I did something wrong.
Best,
