commandButton and commandLink strange behaving

I use <h:commandButton value="ok" action="{#bean.method}"/>

bean.method returns null to stay on same page. when I run it on localhost everything is OK. when I deploy application on server, then action method is never called and nothing is happend (neither exception)

it same is happend with commandLink
