How do I show a mandatory filed based on conditions of Works flow?

[jun lee]

I added "The transition will be allowed if the following fields are completed" as a condition for transition from work flows. It works however user may not know whether that field is a required field for transition. 

Is there a way for users to know whether the field is required (ex. asterisk symbol)?

Hello @jun lee 

What you need is a validator, it will show the transition but when you try to transition the issue if the condition is not met it will show a message (you choose it) you create a validator and add a condition to it. Don't forget to remove the old condition.

 Add a validator

To add a validator to a transition, edit the workflow that contains the transition, select the transition, then click Validators in the properties panel for the transition.

How to add a validator.

From https://support.atlassian.com/jira-cloud-administration/docs/configure-advanced-issue-workflows/#Advancedworkflowconfiguration-validators

To add a validator to a transition:

1. Select  > Issues.
2. Click Workflows and then Edit for the relevant workflow.

3. In diagram mode, select the transition arrow. In text mode, select the transition's name from the Transitions (id) column.

4. In diagram mode, click Validators in the properties panel to show the triggers configured for the transition. In text mode, select the Validators tab.

When you click Add validator, you can choose from the available validators and set any necessary parameters for the validator.
