Is this an open issue? I have three tabs and they are set in callbacks. The first tab loads fine but then the other tabs none of data loads. The layout looks right but no graphs/data.
I was able to solve this. The issue was I was using the children =  structure before and didn’t have to worry about getting callbacks to fire from specific inputs in that Div because they were all firing anyways. Now I just added new hidden divs to fire the callbacks.
