Widget FileUpload

Hola,

espero me puedan ayudar con este error que se me presenta en bonita pm comunnity 7.0.3, antes que nada este procesos funciona bien en la versión 7.0.2

Tengo un proceso en el cual debo de cargar un documento adjunto, defino un documento el cual toma el valor del contrato, el archivo se debe de subir al inicio del proceso, al momento de hacer clic en enviar me arroja el siguiente error java.lang.NullPointerException no entiendo a que se deba esto si el proceso funciona de la misma forma en bonita community 7.0.2 y no arroja ninguna error.
