We see some issue of parsys not showing up for the custom components frequently, when the page refresh or switch the mode (edit to preview, back to edit) parsys is showing.
Application is on Adobe CS. Appreciate, any suggestions.
Can you check if you see any error in browser console. Also please check the below link and see if you are missing something. The below link tries to create a column control with a parsys in it. You can extend the same implementation.
