Exactly, SmallWiki is providing basically the same protocol for HTML generation. However there are two things: - Expressions like "html attributes align: #middle" are not supported yet. You still have to do it the old-fashioned way "html attributeAt: #align put: #middle". If someone wants that, it could be changed easily. - The callback-mechanism of SmallWiki is somehow different, as there is no state in the components: therefor I have to pass into the block/message some more information than just the current value. Basically you register your callback either using a symbol or a block: #messageWithAction:withValue:withMime: (1) (2) (3) or [ :action :value :mime | self foo ... (1) (2) (3) (4) (1) points to the action where the callback is evaluated (2) points to the value of the (input-)callback (this is what you get from Seaside) (3) points to the mime-code of the (input-)callback (4) points to the action where the callback had been defined If your SmallWiki block/message does not take all the arguments, they are simply not given when evaluating.
