I just gave an exam this afternoon, using the gateway/quiz mode.

I found that for some graph theory questions (which work fine in homework mode), where students had to check boxes, neither the student answers nor the correct answer would show up when I clicked "check test", with "Show Correct Answers" and "Show Solutions" both checked.

I could still see the boxes the student had checked, but the usual

Entered Answer Preview Correct Result

array was empty.

Specifically, these problems were in Open Problem Library->Graph Theory->Terminology->Misc.

Library/NAU/setGraphTheory/IsBipartite.pg

Which of the following graphs are bipartite?

Library/NAU/setGraphTheory/IsIsomorphic.pg.

Which of the following graphs are isomophic?

Another problem from Open Problem Library->Graph Theory->Trees->Misc had the same issue:

Library/NAU/setGraphTheory/IsTree.pg

Which of the following are trees and which are forests?

Hopefully that is enough information for anyone interested to duplicate the problem. If not, let me know what additional information I need to provide.

Looking around the forum I saw some mention of similar issues, but could not find the resolution.

Does anyone know of a fix?

Any help/guidance here greatly appreciated.
