If I have defined an optional list custom field on a workflow and a value is entered and the task saved, how can the field be cleared later?
e.g., a "problem" task is created which is initially triaged as a "bug" and the "module" custom field (a list of modules the problem could be in) is set to a particular module.
The problem is later found to be a user error. Consequently the "module" is no longer relevant. However, I can't find a way to select nothing in the "module" list custom field.
