Am not sure, but, whatever job your injected contextlistener is supposed to do, it could perhaps be done in the container listener without ressorting to context listener, isn't it? (using ADD_CHILD for the 'context initialized' and REMOVE_CHILD for contect destroyed)? As for calling init on your injected listern, is suppose you will have to do it yourself.
