We recently installed v2.19 and are working to upgrade from v2.16. Some issues we are seeing in testing are related to display of tables and display of correct answers. Any clues about how to fix them would be GREATLY appreciated. Details below.
[Note: just after posting this I also learned that help boxes are not working - there's no response when clicked. Sounds related?]
I used a modification of the "enter pi" sample PGML problem, combined with a code snippet from an OPL problem (wriitten using PG), to illustrate the issues. My code is here:
#############
DOCUMENT();
loadMacros(
"PGstandard.pl", # Standard macros for PG language
"PGML.pl", # PGML markup and Math Objects
"PGcourse.pl", # Customization file for the course
);
$pi = Real("pi");
$y1=random(5, 20, 1);
$y2=random(21, 50 , 1);
$y3=random(51, 80 ,1);
$y4=random(81,100, 1);
$y5=random(101, 120, 1);
@row1_1= ("\(t\) (seconds)", "0", "1", "2", "3", "4", "5");
@row1_2= ("\(s\) (feet)", 0, $y1, $y2, $y3, $y4, $y5);
BEGIN_PGML
Enter a value for [`\pi`].
[_]{$pi}{5}
showCorrectAnswers = [$showCorrectAnswers]
showSolutions = [$showSolutions]
displayMode = [$displayMode]
END_PGML
TEXT(beginproblem());
BEGIN_TEXT
\{&begintable(scalar(@row1_1)+1)\}
\{&row(@row1_1)\}
\{&row(@row1_2)\}
\{&endtable()\}
END_TEXT
BEGIN_PGML_SOLUTION
You could type [|pi|]* or [|3.14|]*, or [|22/7|]*,
among other options.
END_PGML_SOLUTION
ENDDOCUMENT();
#############
When this code is in the Problem Editor, no answer is entered, and the Show Correct Answer button is clicked the output is:
(Similar results obtain when an answer is entered - the entered answer remains showing in the answer box). It's also the case that the Solution link generates no response.
Using Generate Hardcopy the pdf shows the table correctly, along with the correct answer (showCorrectAnswers=2 because I am using an admin account?):
Setting the display mode in the editor to tex produces this output (showCorrectAnswers=0 because the problem must reload to display tex mode):
{\pgmlSetup Enter a value for \(\pi\). \vskip\baselineskip {\answerRule[AnSwEr0001]{3}} \vskip\baselineskip showCorrectAnswers = 0\pgmlBreak showSolutions = 1\pgmlBreak displayMode = TeX \vskip\baselineskip \par}% \par\smallskip\begin{center}\begin{tabular}{|c|c|c|c|c|c|c|c|} \hline \(t\) (seconds) &0 &1 &2 &3 &4 &5 \\ \hline \(s\) (feet) &0 &15 &30 &60 &91 &107 \\ \hline \end {tabular}\end{center}\par\smallskip %%% BEGIN SOLUTION \par\smallskip{\bf Solution: } {\pgmlSetup You could type {\tt{}pi} or {\tt{}3.14}, or {\tt{}22/7}, among other options. \par}% \par\medskip %%% END SOLUTION
Enter a value for \(\pi\).
\vskip\baselineskip
{\answerRule[AnSwEr0001]{3}}
\vskip\baselineskip
showCorrectAnswers = 0\pgmlBreak
showSolutions = 1\pgmlBreak
displayMode = TeX
\vskip\baselineskip
\par}% \par\smallskip\begin{center}\begin{tabular}{|c|c|c|c|c|c|c|c|} \hline \(t\) (seconds) &0 &1 &2 &3 &4 &5 \\ \hline \(s\) (feet) &0 &15 &30 &60 &91 &107 \\ \hline \end {tabular}\end{center}\par\smallskip %%% BEGIN SOLUTION
\par\smallskip{\bf Solution: }
{\pgmlSetup
You could type {\tt{}pi} or {\tt{}3.14}, or {\tt{}22/7},
among other options.
\par}%
\par\medskip
%%% END SOLUTION
With the code in Undefined Set:Problem 1 and loaded as in an assignment, the Show Correct Answers button gets the same result as shown above for the code in the editor, except showCorrectAnswers=2 as in the pdf output. Debug output for PG Info and Answer Hash Info is below (with the parser-related answer hash omitted, since the lengthy list is essentially all "too deep")
