Runestone Issue: Horizontal Parsons problem using block id when the content of the block is sufficient

[barbarer]

This was in the Practice-SQL assignment in the SI201-W26-TTh ebook on problem parsons-sql-pract-fix. It was giving me an error on the horizontal block arrangement which looked correct.

It thinks the = is in the wrong place. There are two = in the solution. See the Javascript below.

Response from server: 200
runestonebase.js:401 Data from server: {"answer":{"blocks":[0,1,2,3,8,5,6,7,4,9]},"correct":false,"percent":0.8400000000000001,"timestamp":"2026-03-31T16:41:09.725881+00:00","div_id":"mparsons-sql-pract-fix","sid":"barbarer","course_name":"SI201-W26-TTh","id":752225,"comment":"autograded","score":0.8400000000000001} calling repopulateFromStorage

When I switched the two equal signs it worked.

It should be okay if the string in the block matches, even if it is a different block number.

My guess is this is related to work done to support math mode in the blocks.

But, we need someone to step up and be the maintainer for this question type.

But wait... why do you have 2 = blocks in the first place? Arent the horizontal parsons problems written to allow you to use the same block more than once?

Hmm, that was true at one point. I will check with Zihan.

The horizontal parsons do allow you to reuse the blocks; but that is a setting that can be turned on and off for all blocks. Turning it on could solve the bug, but it would also make all other blocks reusable; I'm not sure that's ideal for the students.

I think the original version of checking the strings directly would work, but that if I remember correctly, wouldn't work for math? How about we have a separate option just for math to enable the indices, but for the rest we'll still use the original string to compare for correctness?
