From my understanding I thought that it should be possible to use the bracket notation too but as there seemed to be an issue I set up a test to try and ensure what I am seeing is due to the navigation rules failing to be matched. I setup a simple h:commandLink with an action defined with the bracket notation calling a method that should match with a straight-forward navigation rule, again with the from-action defined using the bracket notation. As expected the method was called successfully but the redirect did not fire which makes it seem as if the rule is not being matched...?
