[jbarrez]

Injection with a string are NEVER resolved. That's why it is a string.

You need an expression. From the user guide:

<code>
<activiti:field name="html">
      <activiti:expression>
        <![CDATA[
          <html>
            <body>
              Hello ${male ? 'Mr.' : 'Mrs.' } ${recipientName},<br/><br/>
                
              As of ${now}, your order has been <b>processed and shipped</b>.<br/><br/>
                 
              Kind regards,<br/>
                 
              TheCompany.
            </body>
          </html>
        ]]>
      </activiti:expression>
    </activiti:field>     
</code>
