[Seaside] Design question for Seaside applications

[Damien Cassou]

Hi,

I would like to guide to reader of my Seaside Book through the creation 
of a blog application. I need the clearest design possible and something 
that is usually found in Seaside applications to make the reader a good 
Seaside developer.

So, the application has a title bar, a menu and a content. I would like 
to change the content component depending on what the user is currently 
doing (editing or viewing a blog). What is the best design for this ?

Currently, I have the root application that renders the title bar, the 
menu and the content. The menu and the content know about the root 
application. When a user click on the menu ('Create a new blog' for 
example), the application change the content component to an editor 
component. But, this component is just rendered as a sub-component of 
the application, it is not called. So, to answer the modified blog 
message, the editor can't use #answer: and directly sends a message to 
the application : #editingDoneWithMessage:

Is it a good design ? What are you advices ?

Please, this is really important to teach good designed application and 
I'm waiting for your advice. I'm sure you want this book to be a good 
entry point to our world.

Thank you
