I don't think so, but I might be wrong.

How do you know this ? I think listItem: expects a block.

You have broke a lot of code :-)

I think this code is wrong, you should have wrote:
html list: self persons do: [:person | html text: person name]
This is because #list:do: expects a block that will render something.
You could use also:
html list: (self persons collect: [:person | person name]). If you have
a look at how #list is implemented, you will see that it sends #text:
for each element.
Did you heard about the new Canvas API ? If you are new in Seaside, you
might to try it because it is the future. Just ask if you want to know
more about this.
Hope I'm not wrong
Bye
