 DEBUG ERROR
[8/27/13 15:17:23:188 BRT] 00000043 SystemOut     O


O erro foi pois eu tinha isso no meu web.xml:

    <context-param>
        <param-name>primefaces.THEME</param-name>
        <param-value>bootstrap</param-value>
    </context-param>

porém eu não tinha a dependência no meu pom.xml para o primefaces-bootstrap.. por isso acontecia o erro..

Abraços!
