Hi folks, I'm having an issue with event listener registration. I figured
out that I need to deregister my listeners after each functional test so
they don't get registered twice in the same thread and execute too many
times. But I was using an anonymous callable to register them, like this:
ok thanks. +1 for adding that in the long term!

Hi Jonathan, sure can, here it is below. I think maybe this has something
