socialengine group-invite doesn't work

membercontroller.php

/application/modules/group/controllers/membercontroller.php 

this actual code:

$count = 0; $multioptions = array(); foreach( $friends $friend ) {   if( $group->membership()->ismember($friend, null) ) continue;   $multioptions[$friend->getidentity()] = $friend->gettitle();   $count++; } sort($multioptions); $form->users->addmultioptions($multioptions); $this->view->count = $count; 

this best option use:

$count = 0; $multioptions = array(); foreach( $friends $friend ) {   if( $group->membership()->ismember($friend, null) ) continue;   $multioptions[$friend->getidentity()] = $friend->gettitle();   $count++; } asort($multioptions); $form->users->addmultioptions($multioptions); $this->view->count = $count; 

or should use code too:

$count = 0; foreach( $friends $friend ) {   if( $group->membership()->ismember($friend, null) ) continue;   $form->users->addmultioption($friend->getidentity(), $friend->gettitle());   $count++; } $this->view->count = $count;
