Here I am generating “resource_prefix” from the previous inputs of “.properties.project_id” and “.properties.env”: "resource_prefix": { "icon": "DefaultProperty", "type": "string", "title": "Resource name prefix (auto-generated)", "description": "Resource prefix based on project and environment.", "default": { "jqQuery": ". form.project.properties .project_id + \"-\" + . form.environment.properties .env" }, "dependsOn": [ "project", "environment" ] }, This works very well. As for potential improvement I would like “resource_prefix” to be auto-generated from the previous inputs and NOT EDITABLE from the user form.
