Hi,

We've tryed the <chatter:feed> component inside a custom apex page and we are having issues with the "rerender" method, the first time that the object is rendered it shows all the feeds but when we try to call to the method <apex:actionFunction> passing the id of the chatterfeed object to the rerender parameter it doesn't retrieve all the feeds from a group.

Here is the code:

Visualforce page:

<apex:page controller="Elogos_ChatterController" sidebar="false" showheader="false">
      <a href="#" onclick="UpdateChatterFeed('xxxx');">Test Chatter Group</a>
      <apex:form >
            <apex:actionFunction name="UpdateChatterFeed" action="{!DoSomething}" rerender="chatterFeed" >
                  <apex:param name="entityId" assignTo="{!EntityId}" value="" />
            </apex:actionFunction>
      </apex:form>
      <chatter:feed id="chatterFeed" feedItemType="TextPost" showPublisher="true" rendered="true" entityId="{!EntityId}"/>
</apex:page>

Controller:

public with sharing class Elogos_ChatterController {

	public String EntityId{get;set;}
	
	public Elogos_ChatterController (){
		this.EntityId = 'xxxx'; // Chatter Group Id
	}
	
	public PageReference DoSomething(){
		return (null);	
	}
}

I hope your help.

Regards.
