灰烬 - 选择错误 - 您修改了＆＃34;聚焦＆＃34;两次

Question

我有一个ember selectize字段 - 当我创建项目时 - 它将它添加为我的下拉确定 - 但它不会自动选择它。我试图设置模型，但是这会产生错误。不确定它意味着什么或如何纠正。

在我的行动中，我有类似的东西

     createItem(item) {
       console.log("create ", item);
       this.set('references', this.get('references').addObject({reference:item}));//add item to references and set the referenc.agenda.method.valuees
       //this line here creates the error.
       this.set('model.campaignReference', item);//set the campaign reference in the model
     },

错误
