I'm looking at: https://nifi.apache.org/docs/nifi-docs/html/expression-language-guide.html
> isEmpty Description: The isEmpty function returns true if the Subject is null or contains only white-space (new line, carriage return, space, tab), false otherwise. This logically implies that isEmpty returns FALSE if the Subject contains NO CHARACTERS AT ALL (not even white-space). This makes no sense at all. >allAttributes Description: Checks to see if any of the given attributes, match the given condition. Hopefully you actually mean "all", not "any". What's funny here is that THESE TWO functions were the ones I initially needed, and your documentation has errors for BOTH of them. I'll expect then to find more errors in your documentation, and will report them to you as I find them. Feedback confirming the errors will be appreciated. Paul Nahay [email protected]
