[LON-CAPA-users] question about entries in the activity log

[Stuart Raeburn]

Bob,

I am assuming the question type was set to "exam" for part 13, because  
/res/sfu/batchelo/chem111/problems/lecture/set7/M.mass.vol.relations.problem  
is a four part problem containing four numericalresponse items (one  
for each part).

The "POST" entries record the value(s) entered by the student in the  
web form when a submit button was pushed -- either typed into a  
textbox in numericalresponse in standard mode, or the value for a  
radio button which is selected, (i.e., for numericalresponse in exam  
mode).

However, in a multi-part problem, each part has its own "Submit  
Answer" button, and the only value(s) which will be stored (in the  
"CSTORE") is/are for the response item(s) belonging to the part for  
which the "Submit Answer" button was pushed.

The activity log shows the following actions:

20:16:47 Submit Answer button pushed for part 11
Value for response item in part 11 (id=12) was: .0045 M

20:21:01 Submit Answer button pushed for part 15
Value for response item in part 15  (id=16) was: 26.56 g

20:23:46 Submit Answer button pushed for part 17
Value for response item in part 17 (id=18) was .282 L

The button was never pushed for part 13, so no submission is recorded  
for response item 14.

However, the radio button for response item 14 (in part 13) was  
checked when the button was pushed for part 15 at 20:21:01, so the  
POST includes a value for "0.593069306930693" for HWVAL_14, but the  
submission is not recorded in the student's submission history,  
because the "Submit Answer" button was not pushed for part 13.
