I have created a custom Email Publisher because I wanted to make the "To" field as Read- Only  . It works fine except -

1. The original email conversations do not get included in the email Body when we Reply  to the email.
2. The "Reply " and "Reply To " buttons under the emails under the All Updates section do not work

<apex:page standardController="Case" showHeader="true">
<apex:emailPublisher id="myEmailPublisher"
 entityId="{!case.id}"  width="500px" 
 title="Send an Email"
 expandableHeader="true"  autoCollapseBody="true"
 showAdditionalFields="true" 
 fromVisibility="selectable"  toVisibility="readOnly" toAddresses="{!case.contact.email}"
 bccVisibility="hidden"  ccVisibility="hidden"
 emailBody=""  emailBodyFormat="HTML"
 reRender="myEmailPublisher" subjectVisibility="editable" subject="Re:{!case.subject}"
 enableQuickText="true"
 onSubmitFailure="alert('failed');"
 fromAddresses=abc@abc.com
 showSendButton="true" sendButtonName="Send Email"  /> 
 </apex:page>

Can someone help me on this urgently

Thanks
