We have a validator set in a Jira workflow upon creation. This validator works when trying to create the ticket in Jira. However, when I test creating a ticket in the Jira Service Desk portal, where the customers would be submitting from, the validator stops the creation but only with a generic message instead of the custom message set in the validator in the workflow. It is important our message appears so they know what they are supposed to fix. 

Even if issues created through the portal show additional information in the error message that is not shown when issues are created through JIRA GUI, like administrator's contact information, I think that validators custom message should be included.

We are using Service desk 3.0.10 and it is still a problem. We turn on fields validator and it just fails to submit the ticket and just sits there. No error message shows up to the user.

-JSD 2.5.9 here, doesn't work. Trying this within JSD: https://answers.atlassian.com/questions/133658/how-do-i-make-the-second-field-of-a-cascading-select-field-required-

Don't link the error message to a specific field. Suggestion is still valid, make sure the error message is shown to the field it belongs to.

It's working fine in jira service desk 2.3
