page loading sections twice or more after commandLink

[Javoso Torso]

Hello,

I am having a weird problem in a JSF project:

moving from a page to the next through a commandLink
and if the user click to the commandLink twice or more
(the page takes some time to load so many users do not wait and click again and again ( ) ,

the following page the page is being built with some sections (JSF sections) repeated and also with some code (visible for the user) like

"size="1" onchange="changeCountry()"> "

or similars and also the content of a selectItem written as text in a line!

Any idea what could be wrong?

Thanks + regards
