and by the way even if we add the id you requested - your code is wrong. It's not allowed to reRender partially rendered components. Only the parents of such components.
@nbelaevski: thank you.
I'll follow the issue.
sorry, I didn't understood "It's not allowed to reRender partially rendered components.".
I changed my code to reRender my r:column's and works (but I need to put rendered options more than I think it should).
thank you all
sorry I've used wrong word :) should be "not allowed to reRender conditionally rendered components."
