Long time annoyance:
Why do Sorters not indicate red / broken when the defined sort is no longer going to work as requested?
During stages of design, I have to proactively seek out Sorters and look “inside” the Sorter to see that the atts it was sorting on have not changed.
Some sort operations are quite critical to the overall job (e.g. sort before duplicate remover) - if it is not working (has red inside), it needs to tell us on the outside of the transformer (and prior to run, like other transformers).
All transformers should notify when something is "off". Are there any others with this behavior?
