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.

What version of ajax4jsf? You need to use > 3.1.0

D'OHH!

element="image" does not work. element="img" does work.

Recommendation: maybe mediaOutput should give some kind of warning when it is an unknown type of element?
