Test this using 2014 theme? With other plugins disabled?
have you “enabled site tracking” in the buddypress settings?
( https://buddypress.org/support/topic/what-does-site-tracking-do/ )

I think I may have a similar issue, and I think there was a thread about this recently, like in the past 3 weeks or so.. I have not whittled it down to a bp-custom issue, or theme issue, or what yet myself – too busy trying to fix more important things at the moment..

interested if you find the issue / resolution – hope these tidbits help to find..

1. Search Engine Visibility should stay unchecked. See your-site/wp-admin/options-reading.php
2. Allow people to post comments on new articles: should be checked
   (These settings may be overridden for individual articles.) -> could be set to of by default on some themes. Posts directory > Choose Post > Quick edit > Allow comments. See your-site/wp-admin/options-discussion.php
3. Site Tracking should be checked. BP Settings > components
4. Blog & Forum Comments should be checked. BP Settings > settings

If you’re testing a fresh BP install, add some content so you’ll see how it’s displayed. BP Default Data plugin is ideal for this.

Take a look at the code below to see how I use the post_comment action to hook my function vp_add_group_activity_comments(), which creates an activity stream item when a user posts a comment and adds it to their group’s activity stream… This is just what we are doing for our site, but if you look at the code you should be able to figure out how to do it for your site….

function vp_add_group_activity_comments($comment_id){

$comment = get_comment( $comment_id );
GLOBAL $wpdb;
$user_id = get_current_user_id();
$user_info = get_userdata( $user_id );

$current_user_group_id = $wpdb->get_var("SELECT group_id FROM ".$wpdb->prefix."bp_groups_members WHERE user_id = '".(int)$user_id."'");

$comment_action = "<a href='".site_url()."/members/".$user_info->user_login."'>".$user_info->first_name." ".$user_info->last_name."</a> posted a comment on <a href='".get_permalink($comment->comment_post_ID )."'>".get_the_title($comment->comment_post_ID)."</a>";

// arguments to pass to the bp_activity_add() function
$args = array(
'action'            => $comment_action,                     // The activity action - e.g. "Jon Doe posted an update"
'content'           => $comment->comment_content,                     // Optional: The content of the activity item e.g. "BuddyPress is awesome guys!"
'component'         => 'groups',                  // The name/ID of the component e.g. groups, profile, mycomponent
'type'              => 'activity_update',                  // The activity type e.g. activity_update, profile_updated
'primary_link'      => get_permalink($comment->comment_post_ID ),                     // Optional: The primary URL for this item in RSS feeds (defaults to activity permalink)
'user_id'           => $user_id,  // Optional: The user to record the activity for, can be false if this activity is not for a user.
'item_id'           => $current_user_group_id,                  // Optional: The ID of the specific item being recorded, e.g. a blog_id
'secondary_item_id' => $comment->comment_ID,                  // Optional: A second ID used to further filter e.g. a comment_id
'recorded_time'     => bp_core_current_time(), // The GMT time that this activity was recorded
'hide_sitewide'     => 0,                  // Should this be hidden on the sitewide activity stream?
'is_spam'           => 0,                  // Is this activity item to be marked as spam?
);

$add_activity = bp_activity_add($args);

// Update the group's last activity
groups_update_last_activity( $current_user_group_id );

return true;
}  
add_action('comment_post', 'vp_add_group_activity_comments' );

Hi there, let’s try to reply to one problem at a time!

Now the posts do appear in activity stream, but not the comments. If i comment on a post, the stream doesn’t show the comments, but if i comment on a post via activity stream, the comment is then seen on a post and on the activity stream.

I guess, this means the BuddyPress “Site Tracking” is active.

1/ WordPress Administration > BuddyPress Settings > Options Tab – Activity Settings section:
Setting ‘Allow activity stream commenting on blog and forum posts’ is not checked. It means when a post or a comment is posted, then an activity will be generated, but it’s not possible to add an “Activity comment” to the generated activities. Just tested with latest WordPress and BuddyPress 2.5.2 and it works as expected:

2/ WordPress Administration > BuddyPress Settings > Options Tab – Activity Settings section:
Setting ‘Allow activity stream commenting on blog and forum posts’ is checked. This means you chose to synchronize comments between the Post object and the corresponding activity object. So a comment on the activity about the post will generate a regular post comment and a regular post comment will generate an activity comment on the activity about the Post. Just tested with latest WordPress and BuddyPress 2.5.2 and it works as expected:

Now @cmavrikas is talking about something else i think. He wants the activity comments to also be displayed like regular activities: in stream mode.
I then advise to use another filter to avoid parsing args / checking the current object of the Ajax querystring:

function activity_comments_stream_mode( $args = array() ) {
	return array_merge( $args, array(
		'display_comments' => 'stream',
	) );
}
add_filter( 'bp_before_has_activities_parse_args', 'activity_comments_stream_mode', 20, 1 );

I just tested it, and again it’s working fine in latest WordPress / BuddyPress 2.5.2…

I advise you to deactivate plugins/come back to a default WordPress theme and do the opposite work to find the plugins or theme that prevents this regular behaviors.

Hello,

how can group activity comments be displayed like regular activities: in stream mode? the code @imath provided works fine for the SWA, but I do not get the same behaviour for group activity stream.

Thank you

Believe me, you are amazing because you use only a few words to inspire others and that is an incredible talent bluey
