I've made a custom Validator for workflow transitions that checks that a given field isn't left empty.
As required, the validate() method of the Validator throws an InvalidInputException when the user leaves the field empty.
Problem: this exceptions is treated as a server error by JIRA and written in the log files and on the console!
Bad user input is not a server error, it is a normal use case... I'd like my validator to behave just like a normal date/time or username validator.
Thanks for any help...
