Hey everyone! Starting to work a little bit using triggers in Salesforce relative to Chatter.

Business Case:

We are trying to update the chatter feed of the Opportunity when a change to a specific field is made. Ideally, we'd like to post the following in the chatter post details.

<OpportunityLineItem Link> -- <Account Link>

Here is the snippet of code that we're working with now:

            if(opportunityFeedPosts.size() == 0 || opportunityFeedPosts[0].FeedPost.Body != bodyText) {
                //System.debug('OpportunityFeed Posts: '+opportunityFeedPosts[0]);
                
                FeedPost opportunityPost = new FeedPost ();
                opportunityPost.Type = 'LinkPost';
                opportunityPost.Title = ''+entries.get(newOLI.Pricebookentryid).Product2.ProductCode+' socket details';
                opportunityPost.Body = bodyText;
                String id = String.valueOf(newOLI.Id).substring(0,15);
                opportunityPost.LinkURL = 'https://cs2.salesforce.com/'+id;
                opportunityPost.ParentID = newOLI.opportunityid;
                posts.add(opportunityPost);
                System.Debug('Got Here but did not post');
                
                FeedPost opportunityPost2 = new FeedPost ();
                opportunityPost2.Type = 'LinkPost';
                opportunityPost2.Title = 'Account Details';
                opportunityPost2.Body = bodyText;
                String id2 = String.valueOf(opp.get(newOLI.OpportunityId).Account.Id).substring(0,15);
                opportunityPost2.LinkURL = 'https://cs2.salesforce.com/'+id2;
                system.debug('got here and it should have posted twice');
                opportunityPost2.ParentID = newOLI.opportunityid;
                posts.add(opportunityPost2);

The Result:

We get two posts where the message title is the same but the post bodies are different. Essentially we get a double post with each having a unique link for one to the opportunitylineitem and the other to the account.

Any help or quesitons are greatly appreciated!
