Hi,

I am having a trigger on feed item which will fetch the account and opportunity id along  with the @mention

i  have a class which will store the @mention , and a trigger which will store the account and opp id

my issue is the trigger is throwing record is read  only on( after insert ) , whereas the before insert is fetching the ids but the @mention gets grad out

my logic needs after insert trigger only

 

MY TRIGGER :

trigger FeedItemTrigger on FeedItem (after insert , after update) {
  
  if(PIPIntelHelper.skipChatterTriggers == true)
    return;
  
  List<FeedItem>feeditemupdatelist = new List<FeedItem>();
  set<id> parentAccountIds = new set<id>();
  
  for(FeedItem fdItem : trigger.new){
    String idStr = fdItem.Parentid;
    if(idStr.startsWith('006')){
       parentAccountIds.add(idStr);
    }
  }
    
  System.debug('parentAccountIds'+ parentAccountIds);
  Map<id,Opportunity> oppty  = new Map<id,Opportunity>([Select id, AccountId  from Opportunity where id in:parentAccountIds]);

  if(oppty.size()>0){
    for(FeedItem fdItem : trigger.new){
      String chatterBody = fdItem.Body;
      Opportunity parentopportunity = oppty.get(fdItem.Parentid);
      FeedItem f = new FeedItem(id = fdItem.id,Body = chatterBody + '\n Account Id is :'+ parentopportunity.AccountId + ' \n Opportunity Id :'+parentopportunity.Id);
      System.debug('feeditemlist'+fdItem );

      feeditemupdatelist.add(f);
    }
    //if(feeditemupdatelist!=null){
    PIPIntelHelper.skipChatterTriggers = true;

   // update feeditemupdatelist;
         system.debug('feeditemlistupdate'+feeditemupdatelist);
   // }
    }
}

 I am able to store the @mention , but the account ids and opp ids are not getting populated , help me what do i need to change in my trigger


Thanks in Advance
