Some thoughts: Pretty sure it’s because we call setState within the render method, which is whatever method returns JSX, return (<stuff>...</stuff>).

I think it doesn’t like that since we pass the setter to the child, then the child renders, and could immediately call setState (if (data === true)), which triggers a re-render in the parent, which triggers a re-render in the child, which calls setState... and causes an infinite loop effectively.

Create wrapper around setter and pass to children https://github.com/intel/dffml/blob/b88424a927f6279191285e2103a2b50b993b1921/service/webui/webui/src/Paperbase.js#L167-L205 https://github.com/intel/dffml/blob/b88424a927f6279191285e2103a2b50b993b1921/service/webui/webui/src/Paperbase.js#L228-L236

Hedge Fund Legend Paul Tudor Jones "5:1 (risk /reward) Five to one means I’m risking one dollar to make five. What five to one does is allow you to have a hit ratio of 20%. I can actually be a complete imbecile. I can be wrong 80% of the time and I’m still not going to lose."
