CKeditor for Vaadin

Hi all, i need an help whit the CKEditor plugin for vaadin.
I’m using a ckeditor Textfield for the body of an email. I added to the email some placeholders (name, surname etc…) and i want to fill them whit the values of receivers (receiver.getName() receiver.getSurname() etc…) based on the relative receiver of the mail.
For the placeholder i just added a plugin so now i can add placeholders to the email but i don’t know how to fill them whit specific values neither how to get a specific placeholder from the email.
Someone can help me?
Thanks in advance!
