Lookaround assertions in regex rules
Does the Match Regular Expression rule support lookaround assertions? I can't get them to work. When I type it into the regular expression field, the text remains red.

Could you post an example that fails?

Here is the regular expression I was trying to use:
^(?=.{8,65})(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).*$
I wanted a rule to test a string to see if it is between 8 - 65 characters with at least one numeric, one lower case, and one upper case.
Since I couldn't get it to work with the Match Regular Expression rule, I ended up writing custom code that uses the Java STRING.matches(regular expression) with the above regular expression. It appears to work as expected.
^(?=.{8,65})(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).*$
