The method session returns an object of type WOSession; Session is a
subclass of WOSession, and so requires a typecast. As you only want
to retrieve the editing context with a method defined in WOSession,
the cast is not required.

OK, a quick Java lesson required :)
What is the difference between the two, i.e. what is the top line
trying to do, that the bottom one skips?
ec = ((Session)session()).defaultEditingContext()
and
ec = session().defaultEditingContext()
Just trying not to be a code monkey, I want to understand what I
am doing :)

Are you sure you are including the right include for Session?
Anyway, you may write only ec = session().defaultEditingContext(),
without the type conversion, because the WOSession superclass has the
defaultEditingContext method.
