Add a warning on ServiceStudio when you have situations like these:
Because when your try to access the webscreen as expected:
You get this message on ServiceCenter:
The file '/<eSpaceName>WebScreen1.aspx' does not exist.
Sometimes, it's not easy to understand that ,by some reason, you have 2 WebScreens with the same name (specially on big and complex Espaces) on different WebFlows.
Credits for this idea also to Edgar Ramos and Vítor Rosário that I found "digging" a bug that was found on a eSpace related to this problem
