In the context of an action $this->$var refers to the variable container
for the resulting view, not the the Actions class instance itself (check
out the __get and __set magic methods for sfComponent). The view then
gets local access to everything in its variable container. By defining
the varibale as a public member to your actions class you are not
assigning it to the view... only the Actions.
