Hi I am working on a problem where I have multiple records of an Object to be shown and each of these records, will have many child records of It's Child Object.
I have chosen AccordianSection to show parent record and A Table to show Children of each.
Also, I need to provide New, Clone and Delete Functionality for each record. Also, an "Expand All | Collapse All" feature.
So, I am using aura:iteration to dynamically generate lightning:accordionSection. I have tried to assign a unique Name to each AccordianSection by using, Id/Name in conjunction with index of iteration, so that I can easily collect the names of AccordianSections while iterating through record list and could assign it to "activeSections" attribute, which will be used by lightning:accordian to expand listed AccordianSections.
But, My observation is, once AccordianSections are rendered, It's name doesn't change, when I Clone or Delete a Record, Even though AccordianSections are rendered properly. event.getParam("openSections") always gives old value.
Because of this Expand All | Collapse All functionality is not working.

Apex Controller Wrapper
public class CampaignWithLineItems{
@AuraEnabled
public Campaign__c campaign {get;set;}
@AuraEnabled
public List<Campaign_Line_Item__c> campaignLineItems {get;set;}
@AuraEnabled
public String campaignFlag {get;set;}
public CampaignWithLineItems(Campaign__c campaign, List<Campaign_Line_Item__c> campaignLineItems, String campaignFlag){
this.campaign = campaign;
this.campaignLineItems = campaignLineItems;
this.campaignFlag = campaignFlag;
}
public CampaignWithLineItems(){
this.campaign = new Campaign__c();
this.campaignLineItems = new List<Campaign_Line_Item__c>{new Campaign_Line_Item__c()};
this.campaignFlag = '';
}
}
Only solution I got till now is to always append new or cloned records at the end of the existing List of parent records, but I don't want to restrict users like this.
