Yes it is expected, but probably not right. The story is following:
First there where only screen modules, i.e. java code that build up a
screen content using Ecs. This is absolutely deprecated, we (as well as
Turbine) don't want screens to be build via Ecs any more!
So I replaced this by a Jsp template mechanism and sort of hacked the
JetspeedJspPage so that it tries to find a MyScreen.jsp rather that a
MyScreen.java. Only for very few screens there is an exception as their
conversion to templates is not straightforward (basically all screens that
display portlets). If you really need to use such a screen, you'll have to
add it to this list of exceptions.
What I figured out only recetly is that there is another keyword "template"
that is meat to be used to set the screen template. So it'd be cleaner to
still search for screens in the modules and for templates in thetemplates
directory. However, in the near future screens are then not used at all but
only templates. (e.g. /portal/template/login).
I think that screens won't be helpful for anything any more: All "view
preprocessing" (i.e. executing of business logic) will be done in
respective actions and the templates will be provided with a toolbox that
allows them to access the data that they need to display.
