Hi Markus!
Thank you for your response!
I tried to do that. But if I add id="something${counter}" where
counter is just a number it stops working at all.
It renders ok. But buttons do nothing - they cannot submit the form.
If I generate ${counter} as it Tapestry does ({"", "_0", "_1", ....,
"_n"}), that I have the same behavior as earlier - it rerenders only
the first "instance" of control at the page.
I tried to use only "id". And "id" and "t:id". Result is the same.
With simple counter as a number it stops working, with tapestry-like
counter it rerenders only the first "instance".
p.s. When I say "first instance" I mean "first render" of component
(Katia, thanks for comments).
