Ok, I guess I was biting off a bit much before. This is what I get when I try and use the sample multiple choice question.

Problem8
ERROR caught by PGtranslator while processing problem file:setAndy/gage.pg

Can't locate object method qa via package "new_multiple_choice" at (eval 44) line 15.

According to Multiple.pm, this is exactly what I should be doing, but it doesn't seem to recognize the method qa.

Ideas?

Hi Andy,

At the moment can't duplicate the behavior here on either of our machines.

Do you have the latest files for courseScript macros? I seem to remember vaguely that I fixed an error like this a month or so ago. The newest files can be obtained from "Download WeBWorK" (there is a link in the left margin). The updates you would need would be at most in the files PGchoicemacros.pl, and List.pm, Select.pm, Multiple.pm -- all of them in courseScripts -- if you are reluctant to upgrade the whole system.

For some reason the object thinks its type is "new_multiple_choice" rather than "Multiple".

Keep us posted about whether this fixes the problem.

Take care,

Mike

According to Global.pm we're running 1.6_01 from 1/8/01. I diffed PGchoicemacros.pl, and List.pm, Select.pm, Multiple.pm between our version and the one I just downloaded from the server, and the only difference was that List.pm had a new "pretty_print" function, so I don't think that's what's going on.

As a matter of fact, these are the only files in that directory that have changed: List.pm, Matrix.pm, PG.pl, PG_CAPAmacros.pl, dangerousMacros.pl, displayMacros.pl

Ideas? Is upgrading still the recommended fix?

Andy

Hi Andy,

I found it -- by pasting your code directly into one of my problems instead of eyeballing the two sets of code. Sorry I didn't have time to do that sooner.

The statement

$mc = new_multiple_choice;

should be

$mc = new_multiple_choice();

I've corrected the example code as well. Thanks for catching this.

Apparently in the first example Perl assigns "new_multiple_choice" as the object type, while in the second it assigns "Multiple" which is what is needed.

Take care -- Mike
