## Use Case

This workflow was originally taken from a submitted request ([JT-2468](https://youtrack.jetbrains.com/issue/JT-2468)).

The user who submitted this issue wanted to force developers to set the fix version when they resolved an issue.

## Modules

When an issue is updated, this on-change rule checks whether the state is changed to Fixed. If true, the rule requires that a value is set in the Fixed versions field.

* If a value is set in the Fixed versions field, the issue is resolved as Fixed.

* If the Fixed versions field is empty, a warning is displayed. The issue is not resolved. The required field is highlighted.

### Require a fix version to resolve an issue

```JAVASCRIPT
const entities = require('@jetbrains/youtrack-scripting-api/entities');

exports.rule = entities.Issue.onChange({
  title: 'Require a fix version to resolve an issue',
  guard: (ctx) => {
    return ctx.issue.fields.becomes(ctx.State, ctx.State.Fixed);
  },
  action: (ctx) => {
    ctx.issue.fields.required(ctx.FixVersions, 'Please set the \'Fix versions\' field!');
  },
  requirements: {
    State: {
      type: entities.State.fieldType,
      Fixed: {}
    },
    FixVersions: {
      name: 'Fix versions',
      type: entities.ProjectVersion.fieldType,
      multi: true
    }
  }
});
```
