Displaying a simple error page from a flow

[Wessel, Keith]

Got it. I'll keep this in mind with my future coding.

Thank you again,
Keith

The setPrincipal method takes a String, and the Function in question returns one, you just have to call it.

Functions are just classes with an apply() method that take an input and return an output. Our functions almost always take a ProfileRequestContext as input. The return types vary by function.

The ProfileRequestContext object is populated in scripts as a variable called "input".

So if you have a Function bean, you call bean.apply(input) to get it to run, most of the time.

Predicates/conditions are the same, they're just like functions that return boolean.
