问题概述：目前正在编写 Lightning 组件以更新自定义对象上的记录。但是，每次我触发更新（通过 ui:button）时，页面都会冻结，并且我在调试器或控制台中看不到任何错误。无法为我的生活弄清楚为什么它不起作用。
上下文：该组件有许多填充有记录的下拉列表（标签是记录名称）。在下拉列表中选择一个新值并点击“更新”会调用下面的顶点来更改新选定项目上的自定义字段 (Status__c = 'Ready')，然后更新它之前出现的记录 (Status__c = 'Complete)。我在初始化期间在另一个函数中进行了所有的安全和更新检查，所以你不会在这里看到（如果需要，我可以发布完整的代码）。只是试图让更新工作。
如果有人能告诉我我的方式的错误，我将永远感激:]。一直是 stackoverflow 的忠实粉丝，现在我终于注册了，期待做出贡献。谢谢大家的时间！

@AuraEnabled
public static void updateMilestones(String deployId,Boolean prodChanged,String newProdMile) {
if( prodChanged == true && newProdMile != null ) {
try {
decimal newProdStepNum;
List <Milestone__c> newReadyProdMile = New List<Milestone__c>();
for(Milestone__c mil1:[SELECT id, Status__c, Step_Order__c FROM Milestone__c
WHERE Deployment__c = :deployID
AND id = :newProdMile LIMIT 1]){
mil1.Status__c = 'Ready';
newProdStepNum = mil1.Step_Order__c;
newReadyProdMile.add(mil1);
}
List <Milestone__c> prodMilesComplete = New List<Milestone__c>();
for(Milestone__c mil2:[SELECT id, Type__C, Status__c FROM Milestone__c
WHERE Deployment__c = :deployID
AND Step_Order__c < :newProdStepNum
AND Type__c = 'Production'
AND Status__c != 'Complete'
AND Status__c != 'Revised']){
mil2.Status__c = 'Complete';
prodMilesComplete.add(mil2);
}
update newReadyProdMile;
update prodMilesComplete;
}
catch (DmlException e) {
throw new AuraHandledException('Sorry, the update did not work this time. Refresh and try again please!');
}
}
}
Javascript：
updateMilestones : function(component, event, helper) {
// update milestones server-side
var action = component.get("c.updateMilestones");
action.setParams({
deployId : component.get("v.recordId"),
newProdMile : component.find("prod-mile-select").get("v.value"),
prodChanged : component.get("v.prodChanged")
});
// Add callback behavior for when response is received
action.setCallback(this, function(response) {
var state = response.getState();
if (component.isValid() && state === "SUCCESS") {
// re-run the init function to refresh the data in the component
helper.milesInit(component);
// refresh record detail
$A.get("e.force:refreshView").fire();
// set Update Changed Milestones button back to disabled
component.find("updateButton").set("v.disabled","true");
// show success notification
var toastEvent = $A.get("e.force:showToast");
toastEvent.setParams({
"title": "Success!",
"message": "Milestones have been updated successfully."
});
toastEvent.fire();
}
});
// Send action off to be executed
$A.enqueueAction(action);
}
