Summary

Custom field values can be set on a per-project and/or per-rule basis in your JEMHCloud profile, where they are called Custom field defaults.

...

Click the little cog beside the project mapping you've elected. Go into the Issue tab and click the Edit button found towards the top right. Scroll down until you see the Custom field defaults section.

Setting a Static value

The simplest way to set a custom field is by passing a static text-format value. Find the desired custom field from the list. Ensure that the drop-down at the end of the row is set to Text, and enter a value to be used for this project mapping/rule.

...

Once a value has been entered, you can then select when this value should be set (issue creation, issue comment, both). Finally, submit the form to save your changes.

Setting a Dynamic value

To set a dynamic value this will require either a Velocity script or a JavaScript Script to gather and set the relevant value.

To set a dynamic value this will require a Velocity script to gather the value. When the script is parsed it will result in whatever value is present in the template after rendering being set as the value for the Custom Field.

Using Velocity

Once the Velocity script is parsed it will result in whatever value is present in the template after rendering being set as the value for the Custom Field. For more information about Velocity see: https://velocity.apache.org/engine/1.7/user-guide.html#what-is-velocity

Velocity Context

When you create a dynamic Custom Field Default, you can make use of special variables found in the ‘context’, see them through:

...

Go to Profile > Project Mapping > Issue > Edit
Under CUSTOM FIELDS DEFAULTS you will see the available custom fields for the project mapping's project.
Find your custom field, select Velocity and when you want the field to be updated e.g. On Create/Comment.

Enter the relevant script within the text-box

See the following page for some example Velocity Scripts: Velocity Script Examples

Using JavaScript

This allows you create Custom JavaScript that will evaluate and set the relevant values to the Custom Field.
