Github user corneadoug commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/480#issuecomment-194783809 Sorry, I had a pile of notifications. It depends on how the error is detected, the best could be to fire the modal on error (if multiple errors, they check if the modal is fired or not), which would suppress the button and be only the modal shown before. The only problem overall would be the timing of those errors (in case you already closed the modal or restarted the interpreter)
