Should I use a condition or validator for this scenario?

[Asl Shushed]

We are trying to prevent users from transitioning an issue without having a particular field filled in. I think a validator is the right choice, but I was wondering if a condition could work if we wanted to go that route instead?

You can use both, but they will behave in different ways. If you use a condition, you will not even have the option to transition through the workflow through the path that you set the condition on. If you use a validator, users will see the option, but will be prevented from transitioning and will be given an error message telling them why they are being prevented.

I prefer to go the validator route because users tend to become confused when they don't see the option they are looking for.
