[Seaside] problem to understand the render: method from book.seaside.st

[Vincent Dautremont]

Hi,
I'm new here, am following the book (http://book.seaside.st)
and have a question about rendering components and getting the answer back from them.

- In section 11.5 (http://book.seaside.st/book/components/calling/answer)
the "answer:" method after a "call:" method is clear for me.

The result of (self call: view) is the object return by the answer: method.


- In section 11.9 (http://book.seaside.st/book/components/calling/show-answer) I've also understood that the same goes with the unblocking method "show:" that create inline html code of the component.

- What I don't understand is how to get the answer back if I call my component with the render: method.
In section 12.2 (http://book.seaside.st/book/components/embedding/example)
the component is now embeded using the render: method and the note and the end of the page refer to section 11.5 to get the answer back from the cancel/save  button.
I don't understand that because (html render: editor) doesn't answer true nor false when I press the save or cancel button.

Thank you for the help.

Vincent.
