I created a plugin that allows the members in a group to have a video chat. When the admin starts the chat a notification is send to all the group members:

bp_notifications_add_notification( array(
'user_id'=> $value,
'item_id'=> rand(),
'secondary_item_id' => $bp->groups->current_group->id,
'component_name'=> 'chat',
'component_action'=> 'new_group_chat',
'date_notified'=> bp_core_current_time(),
'is_new' => 1,
) );

The notifications are saved in the database but are not displayed in the notifications page.
This is the function that sets up the global variables for the plugin:

function bp_group_chat_setup_globals() {
global $bp, $wpdb;

/* For internal identification */
$bp->chat->id = 'chat';

$bp->chat->table_name = $wpdb->base_prefix . 'bp_group_chat';
$bp->chat->notification_callback='bp_group_chat_format_notifications';
$bp->chat->slug = BP_GROUP_chat_SLUG;

/* Register this in the active components array */
$bp->active_components[$bp->chat->slug] = $bp->chat->id;
do_action( 'bp_group_chat_setup_globals' );
}
add_action( 'bp_setup_globals', 'bp_group_chat_setup_globals' );

And this is the notifications format function:

function bp_group_chat_format_notifications( $action, $item_id, $secondary_item_id, $total_items) {
global $bp;
switch ( $action ) {
case 'new_group_chat':

$group_id = $secondary_item_id;
$group_link = bp_get_group_permalink( $group );
$groupSlug=groups_get_slug( $secondary_item_id);
$url=home_url( $bp->groups->slug . '/' .$groupSlug . '/' . 'group-chat' );

if ( (int)$total_items > 1 ){
return apply_filters('log_multiple_verifications_notification','' . sprintf( __( '%s group broadcast invite!', 'chat' ), $groupSlug ) . '',$total_items);
}
else{
return apply_filters('log_single_verifications_notification','' . sprintf( __( '%s group broadcast invite!', 'chat' ), $groupSlug ) . '',$total_items);
}
break;
}
do_action( 'bp_group_chat_format_notifications', $action, $item_id, $secondary_item_id, $total_items );
return false;
}

Any suggestions?
