In the better-late-than-never department, you can use Tomahawk's t:updateActionListener tag to get the same functionality that f:setPropertyActionListener provides. If you were using facelets (which I'm guessing you are not), you could also use the built-in JSF 1.1 facelets f:setPropertyActionListener without JSF 1.2.
