Javascript remoting is disabled after page refresh when using apex email publisher and visualforce templates. This causes javascript-related features to not work unless the page is manually refreshed (i.e pressing F5)

1. enable Email To Case
2. create the following Visualforce Email Template
Name : TestTemplate
Available For Use : check
<messaging:emailTemplate subject="Test" recipientType="Contact" relatedToType="Case">
<messaging:htmlEmailBody >
<body><h1>Test Html!!!</h1></body>
3. create the following Apex classes
global class EmailPublisherLoader implements QuickAction.QuickActionDefaultsHandler {
global EmailPublisherLoader() {

global void onInitDefaults(QuickAction.QuickActionDefaults[] defaults) {
QuickAction.SendEmailQuickActionDefaults sendEmailDefaults = null;
for (Integer j = 0; j < defaults.size(); j++) {
if (defaults.get(j) instanceof QuickAction.SendEmailQuickActionDefaults &&
defaults.get(j).getTargetSObject().getSObjectType() ==
EmailMessage.sObjectType &&
defaults.get(j).getActionName().equals('Case.Email') &&
defaults.get(j).getActionType().equals('Email')) {
sendEmailDefaults =

if (sendEmailDefaults != null) {
EmailTemplate e = [select id from emailtemplate where name='TestTemplate' limit 1];
public class W2847866 {
public W2847866(ApexPages.StandardController cont) {

public static String doTest() {
return 'Hello!!!';
4. configure EmailPublisherLoader class as Default Handler for Email Action
Please refer to for details.
5. create the following Visualforce page
Name : W2847866
<apex:page standardController="Case" extensions="W2847866">
function doTest() {

function handleResult(result, event) {
if (event.status) {
<input type="button" value="DOTEST" onclick="doTest(); return false;"/>
<apex:emailPublisher entityId="{!Case.Id}"
showTemplates="false" emailBodyFormat="textAndHTML"></apex:emailPublisher>
6. access to the above VF page with existing Case id
https://{hostname}/apex/W2847866?id={existing Case id}
You will see DOTEST button and a email publisher.
7. click DOTEST button
You will see nothing occurs. This is not expected.
Please check browser's console. You will see the following error.
Uncaught ReferenceError: Visualforce is not defined

8. reload the VF page and click DOTEST button
You will see alert dialog with "Hello!!!" text.

9. access to BT by other browser and do clear chace for your org
10. reload the VF page again and click DOTEST button
You will see nothing occurs. This is not expected.

Refresh the browser window.
