Announcement: tested it on the LimeSurvey DevDemo https://demo.limesurvey.org/index.php?r=admin as well (Thanks, _olle!) which was running 4.1.16. The bug is still present there.

This issues is blocking us from rolling out our latest, updated survey to our at-th-ready participants. We are not able to properly edit the necessary changes into our survey as the error prevents a successfull save.

You can also

1) Give us a screenshot of "Call to a member function setAttributes() on null"

2) Enable debug = 2 in application/config/config.php and give us a screenshot of "Call to a member function setAttributes() on null" or the full error

I also have the issue, thanks for report.

Fix committed to master branch: http://bugs.limesurvey.org/plugin.php?page=Source/view&id=29817

The problem seems to be the export, not the import.
lterfloth, please apply the fix below, export the group again and see if it can be imported successfully this time.

Wow that was quick. Will try and report back, thank you.

The link you provided is not working. Found the change on GitHub though. Do we just have to overwrite the file for an update?

Update: we applied the fix by just changing line 1943, nothing else. When clicking the export group button, an error appears (see attached screenshot)

You must not have changed the line properly. please try again.

This is the environment/block we changed the line in:

// Questions localization
$qqueryl10n = "SELECT {{question_l10ns}}.*
FROM {{question_l10ns}}
JOIN {{questions}} ON {{question_l10ns}}.qid = {{questions}}.qid
WHERE gid=$gid order by question_order, {{question_l10ns}}.language, scale_id";
buildXMLFromQuery($xml, $qqueryl10n, 'question_l10ns');

I'll get the full export_helper.php-file later today, will attach that one as soon as possible so you can compare it. Again info: we are on 4.1.4, might have to do with that version as well? No chance for us to test on 4.1.16 atm.

Attached the export_helper.php we are using. The file is on version 4.1.4 and no changes were made. Just that single line got replaced according to the sysadmin.

Revert all your changes. We don't offer personal support to non-paying users. Either wait for the release or ask on our forum.

I know that you are not offering "personal support", do not need to put emphasis on that. We are calmly waiting and not pressuring you in any way. Maybe I misunderstood the way you communicate within the bugtracker, sorry for not knowing your culture in this regard. The only thing I did was responding to the requests made by c_schmitz. I do not understand such a passive-aggressive response, as I was only trying to give you as much info as possible.

Hello @lterfloth, we did not mean to answer you harshly - and it definitely was not Olle's intention ^^ .

Regarding your problem, please note that we cannot test in 4.1.4 - all the fixes are provided based on the latest stable version which is at the moment 4.1.16.

Also the issue was not completely solved: the subquestion text is exported, but it does not seem to be imported - If @c_schmitz does not have time for this issue, I will make sure to be part of the next round of bug fixing. (changing status now)

@lterfloth Yeah, sorry, I had a root canal filling this morning, haha. It got to me.

@lterfloth, sorry for the confusion. Please test and let me know if it works now.
If it does not, please add the survey (even with only that one question group) as .lss file (not .lsg) so I can test your case properly. Thank you for your help.

Fixed in Release 4.1.17+200414

Hey there,

I tried reproducing the bug on your demo system ( https://demo.limesurvey.org/index.php?r=admin ) and it was successful. Steps to reproduce:

1. create a new survey
2. import the attached .lsg (in the bug report)
3. go into one question-array of the group, you should see the entries in "Teilantworten" are blank
4. change those entries to whatever you want
5. hit save
6. error-toast appears

Dove deeper:

I exported the .lsg again after applying the fix. Seems like it works now, on 4.1.4 and on 4.1.17 (demo server) as well. So the bugfix seems to be working flawlessly, sorry for reopening and BIG THANKS for the quick fix!

Fixed.
