Reporting 2 bugs and asking a question
"checkErrorsMode": "onComplete", navigating via the progress buttons validates each page."showProgressBar": "hidden" together with "progressBarType": "buttons" does not work, the whole survey is then hidden. This does work when I reset to `"progressBarType": "pages".Also, clicking another page via the progress buttons does not trigger onPartialSend, is this intended? I send data to the backend on each Next click, I would like this to happen as well in case you navigate forward with the progress buttons.
"checkErrorsMode": "onComplete", navigating via the progress buttons should not validate each page."showProgressBar": "hidden" together with "progressBarType": "buttons" should just render the survey with hidden progress buttons, just as it does with `"progressBarType": "pages".Try to navigate to the second page without answering the required question via the progress buttons vs via the Next button in this Plunker: https://plnkr.co/edit/EwobXA46C8GB5g8v
See Plunker above
Hello,
We fixed bug with checkErrorsMode equals "onComplete" in progress buttons case via commit above. And we can't reproduce the issue with progressBarType equals "buttons" and showProgressBar equals "hidden". Here live sample of this setup and all works fine in our case. Does it work for you?

Thanks, Alex

Hi @gologames !
Thanks for your reply and the fix. For me the hidden survey happens when I have these settings:
"showProgressBar": "hidden",
"progressBarType": "buttons",
"mode": "display",
"isSinglePage": true
But I can't for the life of me seem to replicate it in a Plunker :( I do quite a bit of editing in Javascript, so it's difficult to pinpoint the issue. But what I can say is that I do see the survey when I do not have "isSinglePage": true set.
Do you have an answer to my question as to if onPartialSend should be triggered on navigating via the buttons?
Hello,
We discussed with team and implemented calling onPartialSend event via progress buttons too by the commit above. We'll check isSinglePage mode and write back to this thread immediately

Awesome, great to hear! I'm excited to try it out when it's released :+1:
I hope you can replicate the issue, for me it's not a big problem, since it does work with "progressBarType": "pages" and I hide the progress bar on my read only page anyway. So with the bugs fixed I'm happy to release my progress bar change to production soon. Great work y'all!
Hello,
We usually release new version every Tuesday. So, you can wait this changes on next week with 1.8.25 version. Use our Whats New page to track the new releases. We'll update this thread after investigating isSinglePage mode case

Hello,
We tried, but we also can't reproduce hiding survey issue which you had described above. Here is live sample in plunker with SurveyJSON setup which you had provided

Good news is that for some reasons we already released new 1.8.25 version. I've updated your first live sample and all works fine now, you can check

Thanks, Alex

Yes I have tried to reproduce it on Plunker but I couldn't. I don't see any errors either, and the whole survey is actually present in the DOM, it is just hidden somehow, since I don't see anything. Super weird.
I have tested v1.8.25 and it indeed works perfectly, thanks a lot! And have a nice weekend to you all!
Hello,
Great! I close this issue so as we can't reproduce any problems. Feel free to create another issue if you will face with any troubles

Hi there!
Sorry to bother you again, but I have found 2 more issues with "progressBarType": "buttons".
When onServerValidateQuestions is implemented (with setting "checkErrorsMode": "onValueChanged" for example or at least not on "onComplete":
sv_progress-buttons__list-element--passed.I have been able to reproduce it in this Plunker:
https://plnkr.co/edit/lJLvVsRbuBDvK21V
As you can see in the above Plunker:
P.S. @gologames If you want me to create a new issue, I will, just let me know :+1:
I've created separate issue and will update it after investigation
