Session gets stuck on "Sending Data Please Wait"

YotamF

In my experiment, the user needs to have a minimum connection speed, and we are also checking if he's paying attention.

If a user fails to meet one of the previous criteria we finish the session with

jatos.submitResultData(result_json).then(jatos.endStudyAjax(false,err_msg));

But the session gets stuck with "Sending Data. Please Wait." and a spinning wheel.

Has anyone else encountered this problem and\or knows how to fix it?

Yes, it's a bug in the current jatos.js (version 3.6.1). In some cases with jatos.endStudyAjax or jatos.abortStudyAjax this can happen. The next release (should be 3.7.1) will include the fix.

Until then you can use jatos.removeOverlay to remove the "Sending Data. Please Wait." with a spinning wheel. In your case it should look like:

jatos.submitResultData(result_json).then(jatos.endStudyAjax(false,err_msg)).finally(jatos.removeOverlay);

Hope this helps,

Hi Kristian, thanks for the response, unfortunately, it doesn't seem to fix the problem.

Do you happen to know if there's an earlier version where the bug doesn't exist?

And on that note, do you know if the bug exists in the current jatos.js version which is on mindprobe?

Hm, it doesn't fix the problem ... do you have an error message or is there no error? Or can I somehow have a look at your study? If it's possible you could send me your study (the exported jzip) or make me a member of your study on jatos.mindprobe.eu (my username is 'admin').

And about your other questions: Version 3.5.10 should not have this bug. And, yes, mindprobe also uses version 3.6.1 and there jatos.js has the bug.

I had a look at your study. It's more complicated than I thought. My idea with jatos.removeOverlay does not work. But fortunately there is way to completely turn off those overlays from the start. Just add jatos.waitSendDataOverlayConfig = { show: false }; in the beginning of your jatos.onload:

jatos.onLoad(function() {
  jatos.waitSendDataOverlayConfig = { show: false };
  ...

Hope this helps this time.
