I was able to implement Resource Header Click using Javascript in version 7.6, however, when I move to version 7.9, it does not work anymore. It gives a JScropt error: 'ctrlKey' is null or not an object. The error seems to come from daypilot-all.min.js .... $e.$97(r,ev.ctrlKey,ev.shiftKey,ev.metaKey)
What did I miss when I move from 7.6 to 7.9?
Thank you.
