The word "evaluated" here, I don't think it means what you think it means.
Whenever you have a CF statement, the entire statement is evaluated.
So, if you have something like this:
function(variable)
CF is going to verify that the variable exists, because you're referring to it.
That's what's happening here. Just because you're using the DE()
function doesn't mean that CF isn't going to evaluate
importData.nickname at runtime to verify that there's actually
something called importData.nickname in case it needs to reference
that value.
