Require minimum length in field with JSU

[Philipp Tauber]

I'm trying to restrict the length of the description field. I'v already found the following solution but I'm not able to tweak it to my needs.

https://confluence.atlassian.com/jirakb/using-workflow-regular-expression-check-validator-to-restrict-text-field-in-number-format-859509784.html

My understanding is that I would have to change the expression like that:

^[0-9]{160-255}$

The descritionfield should have a length of 160-255 and you should be able to enter anything, lower case / upper case / numbers / ....

But i will always get an error:

We can't create this issue for you right now, it could be due to unsupported content you've entered into one or more of the issue fields. If this situation persists, contact your administrator as they'll be able to access more specific information in the log file.

Which is not the error message I wrote which confuses me further.

I think something is wrong with this regular expression that you are trying to use...

^[0-9]{160-255}$

Overall it would allow only numbers.

Please try to use this one instead:

^.{160,255}$

Thank you that worked like a charm.

Glad to hear that :)

This is working great if we have only one paragraph, but once we press "Enter" and add another paragraph it won't work and the error appears.

How to fix this issue and allow adding new lines while checking the expression?

Hmm.. The error seems similar to this problem - https://confluence.atlassian.com/jirakb/can-t-create-issues-due-to-script-runner-for-jira-being-disabled-899429413.html . Are you using Script Runner for JIRA plugin? If not could you share screenshots from your workflow configuration (validators and post functions) on the transition that you would like to validate?

Thank you for your reply.

I have checked the suggested solution from your ticket, since we run scriptrunner, but unfortunately that didn't help.

We are currently running the trial version of scriptrunner, but there should be no restrictions?

[Mirek]

Could you then share screenshots from your workflow configuration (validators and post functions) on the transition that you would like to validate and create screen? Any errors in the JIRA logs?
