[jboss-user] [JBoss Seam] - ajax4jsf mediaOutput in Seam?

[EricJava]

I'm trying to use mediaOutput in Seam: (1.2.1):

<a:mediaOutput element="image" cacheable="false" session="true"
  |                                createContent="#{chartGenerator.paint}" 
  |                                uriAttribute="src"
  |                                value="#{chartParameters}" mimeType="image/png" />

The chartGenerator.paint method never gets called; the whole thing is ignored.  In fact if I change the name "paint" to something else that isn't even a method on that class, it doesn't throw any exceptions or do anything.

I searched around the documentation and couldn't find references on this.

I realize that using object serialization to pass in a value is very un-Seam (unseamly?).

What's the right way to do this?  I could set up a Servlet to generate the image but that's even more unseamly.
