JSF 2 - Action executa apenas na segunda vez

Olá galera,

Alguém poderia me ajudar numa duvida que me persegue e que não consigo entender.
É o seguinte... Tenho a seguinte estrutura de layout e em alguns momentos quanto tento acessar os links para alterar de pagina, é preciso clicar mais de uma vez para a action seja executada e seja renderizada.
Este problema geralmente ocorre quando acesso alguma pagina através do menu e em seguida tento acessar alguma outra através dos links exibidos no conteúdo.
O que parece é que a primeira vez que clico no link a pagina apenas realiza um refresh, e a segunda vez é que realmente a ection é executada.

Obs.: O mesmo ocorre utilizando apenas JSF 2 (sem RichFaces).

Fico muito grato com a ajuda.
