Sure. Done. The new build is 151215. The "bug" is still here (see second attached file).

Hi,
Yes, can reproduce the issue ...

Starting with newtest=Y : OK last group still YES (or NO)
Starting without newtest=Y (without close browser): last group become "No answer".

I cannot reproduce this. What I did:

1. Create new survey with one question
2. Set options as described above
3. Generate tokens
4. Send e-mail
5. Click on link in e-mail and submit survey
6. Answer is in database table lime_survey_44857
7. Click again on link in e-mail
8. Answer is still in database table

Think you need, at minima 2 group. Tested with included lss file.

OK, I've been able to reproduce both with imported survey and with my own survey. Will fix.

For my own info, this problem does NOT occur if you clear the cookies before re-clicking on the link in the e-mail. The last question group is stored in the cookie as $LEM->currentQset, file em_manager_helper.php (function ProcessCurrentResponses).

Solution 1: Deleting NavigateForwards() on line 270 (?) in file SurveyRuntimeHelper.php? (There's another bug where $seq == -1 even if welcome page is set to No.)

Solution 2: Never save NULL values to database (but does NULL represent "No answer"?)

Solution 3: Make sure no saves are done when clicking on the mail link. NavigateForwards() should be separated from saving in that case.

Solution 4: Clear cookie after survey submit.

Fixed by changing NavigateForward to JumpTo in SurveyRuntimeHelper.php, lines 268-272. Will this break anything else?

Yep : NavigateForwards is a bad idea, we jump, we don't navigate :)

I had to revert that patch because it caused the second question to be skipped if the first one was hidden. You will need to take another look at it.

Carsten : a little lss file ? ;).

It's for Q by Q survey ?

Second solution could be to correctly clear the session after survey submission. Dump $_POST and $_SESSION to inspect. OR: Clear session at survey start. OR: Clear session before navigating forward.

This bug is still present even in last release (v.3.7.1, build 180424).
Is there some forecast about a fix?
I can't ask partecipants to clear cookies after a submission.
Is there some workaround I can use?
Thank you

Tuff one. I might have time to look at this again the coming week.

@olle, is this still an issue at the latest 3.1x version?

@Mazi, AFAIK, yes.

Unable to reproduce this issue using the latest version 3.15.1, it may be already fixed.

I am able to reproduce this issue after all, would try to fix it.
