I have observed unexpected behavior for isusernametaken function. When we pass an empty string to it, it returns true.
As per my understanding this should not be the case. isusernametaken should return true for only the users which exist (activated/deactivated) in the system. This was observed on Appian 7.11
fn!isusernametaken("") - true

The behavior is unexpected. It should not return true when passed a null string. I have logged this to our product team for further investigation. The previous suggestions to work around this are great suggestions, so for the time being, I would consider following those.
