I know there are a lot of posts about this issue...but really...this needs to be resolved. It is actually causing extended development time now. As with everyone else, I can't replicate. It is random. Sometimes it happens, sometimes it doesn't. No difference between type of container (flex, coord, etc.).
I can copy json and paste it to a new Gateway or view and I can open it...sometimes.
IA - please focus more resources on this. It is unacceptable for this to occur. I'm starting to consider investigating other software because of it.
I'm currently working on trying to replicate the issue more consistently and hopefully find a root cause. I wanted to confirm that what you're seeing is the same scenario as currently outlined in our internal bug ticket. For that, would you be able to share the stacktrace from the designer console? If you didn't save it, could you grab a copy of it if you run into it again?
Also, if you have any specific projects or views that run into this issue more frequently feel free to reach out to support to provide exports of those and mention this thread. That will also allow you to be automatically notified when we have a fix.
Just wanted to send a quick follow-up to this issue.
All tickets that went through support and were linked to the internal bug ticket had the same preceding error in the Designer console. This error showed the rootViewDefaultSize being undefined and resulted in the view not loading. Then when closing the view, the Unable to get the view config: View config is undefined error message would be displayed. The root cause was determined to be a race condition when opening views. A fix has been merged and will be available in 8.1.44.
If anyone is consistently seeing this issue, but have a different error unrelated to the rootViewDefaultSize the best course of action would be to reach out to support for further investigation.
