If put some components inside an array component, the script like enable will not work.
Maybe need to specify both the array index(or just default to current?) and name?

Demo code:
fields: { component: 'array', label: 'array label', name: 'array_history', layout: 'vertical', arrayType: 'arrayOfObject', fields: [ { component: 'radio-group', label: 'Do you?', name: 'do_you', options: [ { value: 'yes', label: 'Yes', }, { value: 'no', label: 'No', }, ], row: false, script: "if (do_you === 'yes') { enable(comment) } else { disable(comment) }", 'react-antd': { optionType: 'default', inline: true, }, }, { component: 'input-text', label: 'Comments', name: 'comment', disabled: true, 'react-antd': { fullWidth: true, }, }, ], }

Error: [LetsForm] Error in script: Error: Field "undefined" doesn't exist in the form
