I have an email template that needs to show a cascading fields value if not empty. I've tried {{#if not(issue.fields.customfield_12909.value.isEmpty)}} or just {{#if issue.fields.customfield_12909.value}} and neither evaluates to true or false. I can add the field data to the email using {{issue.fields.customfield_12909.value}} - {{issue.fields.customfield_12909.child.value}} so I know it works in the email but it will just not evaluate in an #if statement.
Looking forward to any help.
