Description of problem: Most commons that I have ran into are "var" and "end". rule test when Event( start:date) Event( end:date) // This actually still works ok then end.anyFunction(); // Does not reopen in guided rule editor end Additional info: In 5.x we added the dollar sign on front of each variable to avoid this. end became $end. This might be a lot of work with what we have now. Another option is to block the user from adding reserved words.
