I am also using @Environmental but it is not availiable at all times. e.g. when the nested component contains a form and that form is submitted... So in order to deal with it I use @Persist, first time around and on form submission I use the persisted value as the environment does not contain the context...
What i was asking is, whether what I am doing is the way to go or there is any other alternative. regards Taha On Tue, Apr 12, 2011 at 3:47 PM, Kristian Marinkovic < kristian.marinko...@porscheinformatik.at> wrote: > Declaring all possible values as parameters leads to high coupling.
