Reading a cookie in component constructor?

[Ondrej Zizka]

Hi,

I have a component which sets a cookie in ajax response, and uses that
cookie when rendering upon further requests to the page.
But it doesn't work. Is there something wrong on the code below?

I have checked that the cookie is set - Firefox's Web Developer plugin
shows it in successive requests.
But when debugging, the cookie is not there (null returned).
Maybe cookies are not avail at the time of components construction?
(Sounds improbable.)

Thanks,
Ondra
