[Seaside] #render: or #call: components.

[David Zmick]

I know that this is probably a very bad practice, but I have initialized
component, eg. a instance variable 'bodyComp'

ok, I will show some code:

RootComponent>>initilaize
   super initialize.
   self bodyComp: BodyComponent new.

RootComponent>>renderContentOn: html
   "all the head stuff"
    bodyComponent renderContentOn: html
    "etc."

I was wonderering how this was "correctley" done the other day, so I'm glad
this thread popped up..  What is bad about my method, if anything, I just
think it seems a little hackish...
