The @Repository annotation is a marker for any class that fulfils the
role or stereotype of a repository (also known as Data Access Object
or DAO). Among the uses of this marker is the automatic translation of
exceptions, as described in Exception Translation.
Spring provides further stereotype annotations: @Component, @Service,
and @Controller. @Component is a generic stereotype for any
Spring-managed component. @Repository, @Service, and @Controller are
specializations of @Component for more specific use cases (in the
persistence, service, and presentation layers, respectively).
Therefore, you can annotate your component classes with @Component,
but, by annotating them with @Repository, @Service, or @Controller
instead, your classes are more properly suited for processing by tools
or associating with aspects.
For example, these stereotype annotations
make ideal targets for pointcuts. @Repository, @Service, and
@Controller can also carry additional semantics in future releases of
the Spring Framework. Thus, if you are choosing between using
@Component or @Service for your service layer, @Service is clearly the
better choice. Similarly, as stated earlier, @Repository is already
supported as a marker for automatic exception translation in your
persistence layer.

I'm not sure if I understood what you've said, but you can do this at your xhmtl:
This will store the value of your selectOneMenu into your flowScope. You can also try other scopes, according to what you want (viewScope, flashScope, etc ... - take a look at SWF documentation).
