How to refer one chatter:feed component for two custom objects in a page?

Question

Could you please suggest on this?

Requirement is to create a "News Feed" page for records from two custom objects. I am able to use a component to get the feeds for records from one object but could not use an additional chatter:feed component for another custom object since the page limits does not allow to use more than chatter component in the same page.

Hence, I thought to find a way to use one chatter component , but dynamically reassigning the object for which the Chatter feed will present it's information.? But I am little confused with this thought too since the default page itself should list the feeds related to both the objects. Any suggestion please how we can approach this scenario?

Thanks in advance!

Answer 1

There isn't a way to custom aggregate FeedItem's from two separate parents using the Chatter Feed component. You can have only one EntityId, which can be a group, topic, user or record.

One idea to workaround this is to auto-assign the posts (with an apex trigger) on those two records to a topic and you could use the Chatter Feed component to show the topic feed. Then EntityId field that points to the parent for the feed can accept a Topic Id.

It's simple enough to fetch both objects in a custom controller (or controller extension) and put both feeds on the same page.

Controller:

public class with sharing MyController {
   Account theAccount;
   Contact thePrimaryContact;
   public MyController() {
     // do stuff to initialize the Account and Contact...
   }
}
