Erro de upload que nem debugar debuga

Galera, esse é o primeiro post que faço e é logo o primeito tópico tambem, to com uma bronca que é o seguinte:
To querendo fazer um upload usando o fileUpload do tomahawk juntamente com o facelets, eu rodo o projeto a página abre normal, o problema é quando eu dou o submit do arquivo que a pagina só dá uma piscada e some o caminho do arquivo do campo de texto, ja tentei debugar mas ele nem entra no metodo, alguma luz por favor!!!!
