取回後無法訪問的值

Question

在SugarCRM 7.2.2中進行驗證時，我將以下代碼放在Team和那裏的用戶，但行var myTeamusers = userTeam2.getRelatedCollection（'users'）;返回null。奇怪的事情是相同的代碼在Chrome控制檯上工作。

var userTeam2 = App.data.createBean('Teams',{id:'e8566565-0d27-2f09-edf5- 52c67c376d41'});//WORKING FINE 
userTeam2.fetch();//WORKING FINE 
var myTeamusers = userTeam2.getRelatedCollection('users');//WORKING FINE 
myTeamusers.fetch({relate:true});//WORKING FINE 
alert("two"+ myTeamusers); // HERE RETURING NO VALUE I.E. LENGTH OF TEAM IS 0 HERE BUT WHEN RUN ON CHROME CONSOLE SHOW IT 4 USERS IN TEAM 
myTeamusers.toJSON(); 
alert("three"+ myTeamusers.toJSON()); 
alert("four"+ myTeamusers.toJSON().length);//SHOW IT 0 

請告訴我，什麼是錯的上面的代碼，我已經在上面定製/模塊/案例/客戶/基/視圖/記錄代碼中使用/ record.js

你應該後訪問userTeam2抓取完成。使用success回調：

userTeam2.fetch({ 
    success: function() { 
     userTeam2.getRelatedCollection('users'); 
    } 
});
