I am getting this error in the inline vf page:

Controller not found for 'CloudFilesController'

while no such error comes when I open the vf page directly without using it as inline page.

VF page:

<apex:page showHeader="false" sidebar="false" standardController="Lead" extensions="CloudFilesController">
  <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/knockout/3.2.0/knockout-min.js"></script>
  <script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

       var loadFiles = function() {
                function(result, event){
                    if (event.status) {
                    } else {
                        console.log('some error occurred');


public with sharing class CloudFilesController {

    public CloudFilesController(ApexPages.StandardController controller) {


    public static List<CloudFile__c> getFiles() {
       return null;

I just needed to make my method and class global in the controller. Thanks to this answer Need help understanding why my Javascript remoting doesn't work on a standard Page Layout


The SFDC doc say something about this:
enter image description here

  • The controller and action exists. It's not just a warning, functionality is also not working
