In case anybody is wondering, this is smalltalk and Seaside.

Nice idea, but it doesn't work. It should be something like this:

    renderContentOn: html
                [html form: [html textInput callback: [:v | said := v]. 
                html submitButton]]
                    ifNil: [html anchor callback: [clicked := true]; with: 'click here']
                    ifNotNil: [html text: 'You said: ', said]].
A more elegant implementation might use the lower levels of Seaside directly, and dispense with components completely. But Arc is about brevity, not elegance, right?

Well, even that code omits the definition of "said" and "clicked". (The latter is unnecessary as far as I can see.)

I agree that mine isn't precisely by the spec -- you have to press 'enter' to submit the form, and there's an ok button on the last page -- but these are fairly trivial differences in presentation due to the behaviour of the built-in libraries.

(also, minor footnote: I'm assuming that "foo", "said" and "clicked" are instance variables in each example.)
