I recently just upgraded to the newest beta version and noticed that some of my FME Hub transformers were stated as "incomplete". I looked at the parameters and couldn't tell why it wasn't working anymore. I then rolled back to the latest release version and had the same issues as well. Is there an easy way to trouble shoot why some functionality would break? I just ended up rolling back to a previous version that works correctly for the time being.
The transformers that are giving me issues are the RegexAttributeSplitter and AttributeConcatenator.
