当我尝试通过传递一个新对象来更改表单对象时，formio 无法正确呈现表单这是一个演示：
angular
.module("formioApp", ["ui.bootstrap", "ui.select", "formio", "ngFormBuilder", "ngJsonExplorer"])
.run([
"$rootScope",
'formioComponents',
'$timeout',
function(
$rootScope,
formioComponents,
$timeout
) {
$rootScope.change = function () {
console.log('Changing the form');
$rootScope.form = {"components":[{"input":true,"label":"Valider","placeholder":"Libellé du bouton","tableView":false,"key":"submit","size":"md","leftIcon":"","rightIcon":"","block":false,"action":"submit","disableOnInvalid":false,"theme":"primary","type":"button","$$hashKey":"object:357"},{"input":true,"tableView":true,"inputType":"number","label":"Numéro point d'analyse","key":"numropointdanalyse","placeholder":"","prefix":"","suffix":"","defaultValue":"","protected":false,"persistent":true,"clearOnHide":true,"validate":{"required":false,"min":"","max":"","step":"any","integer":"","multiple":"","custom":""},"type":"number","$$hashKey":"object:548","conditional":{"show":"","when":null,"eq":""}},{"input":true,"tableView":true,"label":"items","key":"selectField","placeholder":"","data":{"values":[{"value":"1","label":"1","$$hashKey":"object:366"},{"value":"2","label":"2","$$hashKey":"object:369"},{"value":"3","label":"3","$$hashKey":"object:372"}],"json":"","url":"","resource":"","custom":""},"dataSrc":"values","valueProperty":"","defaultValue":"","refreshOn":"","filter":"","authenticate":false,"template":"<span>{{ item.label }}</span>","multiple":false,"protected":false,"unique":false,"persistent":true,"clearOnHide":true,"validate":{"required":false},"type":"select","$$hashKey":"object:312","conditional":{"show":"","when":null,"eq":""}},{"input":true,"tableView":true,"label":"","key":"selectboxesField","values":[{"value":"firstElement","label":"first element"},{"value":"secondElement","label":"second element"},{"value":"thirdElement","label":"third element"},{"value":"fourthElement","label":"fourth element"}],"inline":false,"protected":false,"persistent":true,"clearOnHide":true,"validate":{"required":false},"type":"selectboxes","$$hashKey":"object:201","conditional":{"show":"","when":null,"eq":""}},{"input":true,"tableView":true,"inputType":"text","inputMask":"","label":"Exemple d'un champs","key":"fieldexample","placeholder":"Exemple d'un champs","prefix":"","suffix":"","multiple":false,"defaultValue":"","protected":false,"unique":false,"persistent":true,"validate":{"required":false,"minLength":"","maxLength":"","pattern":"","custom":"","customPrivate":false},"conditional":{"show":false,"when":null,"eq":""},"type":"textfield","$$hashKey":"object:16","clearOnHide":true},{"input":true,"inputType":"checkbox","tableView":true,"hideLabel":true,"label":"check this","datagridLabel":true,"key":"checkthis","defaultValue":false,"protected":false,"persistent":true,"clearOnHide":true,"validate":{"required":false},"type":"checkbox","$$hashKey":"object:151","conditional":{"show":"","when":null,"eq":""}},{"input":true,"tableView":true,"label":"files","key":"files","image":true,"imageSize":"200","placeholder":"","multiple":false,"defaultValue":"","protected":false,"persistent":true,"clearOnHide":true,"type":"file","$$hashKey":"object:431","tags":[],"conditional":{"show":"","when":null,"eq":""}},{"input":true,"tableView":true,"label":"Champs de paragraphe","key":"message","placeholder":"Qu'est ce que vous pensez?","prefix":"","suffix":"","rows":3,"multiple":false,"defaultValue":"","protected":false,"persistent":true,"validate":{"required":false,"minLength":"","maxLength":"","pattern":"","custom":""},"type":"textarea","conditional":{"show":false,"when":null,"eq":""},"$$hashKey":"object:17","wysiwyg":false,"clearOnHide":true},{"type":"button","theme":"primary","disableOnInvalid":true,"action":"submit","block":false,"rightIcon":"","leftIcon":"","size":"md","key":"submit","tableView":false,"label":"Enregistrez","input":true,"$$hashKey":"object:18","placeholder":"Libellé du bouton"}],"display":"form"}

您应该单击“更改”按钮来触发新对象
