In a nutshell the issue is, We've implemented custom email publisher action where we are using publisher js. We are populating email body with the response received with publisher js but its not getting updated. It was working fine till API version 32 but since version 33 its breaking.

Some more pointers on the events which we see while calling this functionality. It looks specific to Custom Publisher action called Send_Email on Case object which contains a visualforce page that has apex:emailPublisher tags.

Following are the javascript events that works on Winter 15 and doesnt work on Spring 15
