[DISCUSS] Skip empty configuration screens in enduser UI

[Matteo Di Carlo]

Hi all,
I worked on SYNCOPE-941 issue - Skip empty configuration screens in 
enduser UI - and I'd like to discuss about mine and other possible 
solutions, in particular about a consequence I ran into.
Since (in edit) the user is able to navigate not only through 
navigation buttons but also through the breadcrumb, I decided to build 
it dynamically to skip empty screens by not showing the related links 
at all on the breadcrumb.

The problem is: during the first initialization of the breadcrumb, in 
Credentials, the user can see clearly the breadcrumb'structure changing 
while it is initializing.

I have tried to fix this using a spinner that disappears once the 
breadcrumb is ready but technically and graphically I didn't find it a 
good solution. SYNCOPE-955
Another way to solve it could be leaving the breadcrumb static as it 
was and disabling those buttons related to empty screens.

Any thoughts?
Matteo.
