I updated to the current SD2 version today. Now I got the problem, that in the preview (phone canvas) I often see a blank page, instead of the panel-content. In the previous version I could select the items (buttons etc.) and change some settings and see how it looks.
This problem does not exist in every panel - sometimes I see the content... If it helps, I would send my project files to a developer, so that you could debug it. But maybe you are aware of the problem already.
Hey there - just wanted to follow up and let you know that I'm now running on build version 298 and that I'm still experiencing the same issue. However, I am able to create new components which appear in the preview. It seems to be that all of my existing components are not displaying though. I can duplicate those existing components and they will reappear. All of my components are inside of a tab panel component.
Please let me know if you have heard of this or have any suggestions.
