This part I can actually do myself, and in Aida, I even understand...

AObjectApp>>viewMain
>        ....
>        self observee dynamicVariables do: [:each |
>            e addtext: each key, ': ', each value; addBreak].
>        ....


But how do I bind one of these dynamicVariables to a
WebInputField/WebCheckBox/etc...?

AObjectApp>>viewMain
     | field |
     .....
     self observee dynamicVariables do: [:each |
          field := WebInputField new aspect: ??? for: self observee
dynamicVariables size: 50.
          e add: field.  e addBreak].

I think I am missing something fundamental again...I mean, I do not know the
"aspect" until the user creates it...
