> In a lot of cases, folks will want to use viewContext.getUsername with their
> view instances parameters. Right now, we leave that logic + code to the view
> developer. We should support parametrization of view instance params to
> handle this, and provide username as the first supported param.
> For example, say I have a parameter "view.path" : "/tmp/some/path"
> In my view, I want to append username, so I have logic in my view code to get
> view.path and + viewContext.getUsername()
> viewContext.getProperties().get("view.path") + "/" + viewContext.getUsername()
> resulting in /tmp/some/path/horton
> If views support parametrization, i could do this:
> "view.path" : "/tmp/some/path/$
> {username}
> "
> then all I need to do viewContext.getProperties().get("view.path");
