Views Fusion not accessible by the view service (service module)

Hello,
I am developing a flex web site using drupal as the CMS. But i can't access to the fusioned views trough the service module. The view.getView service returns the results of the first view, and not the fusioned views. For example, i have two views, v1 and v2, and i use the fusion module to fuse then together. If i use the view.getView service, i get only the v1 results.
I tried to write a new service (getFusionView) inside the view_service.module, but i didn't understand the fusion module, i don't really understand how it works. For example, it uses the cache view to tell the system that v1 is actually a fusion view?? How the system knows that v1 is a fusion view??
Any help is appreciated. Sorry if I'm asking something dumb, i am new to drupal.
Thanks,
Rodrigo
