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}, 

 As of ${now}, your order has been processed and shipped. 

 Kind regards, 

 TheCompany.
 </body>
 </html>
 ]]>
 </activiti:expression>
 </activiti:field>
