[CentOS] RHEL 7 Beta Hidden WIFI issue

Im having problems connecting to Hidden WIFI networks on my RHEL 7 beta. 
I have an HP Elitebook 2560p. 
But if I make the Wireless Access Point visible, im able to connect to it,
and NM is able to save the connection script under
"/sysconfig/network-scripts". 
I tried on 3 different Hidden Networks, 

The solution was to manually create the connection script  in
"/sysconfig/network-scripts".after copying one from a network I had
connected to. That's when the hidden wireless became visible and im now
connected.
But is this the way one needs to connect to a hidden Wireless?
I thought having SSID, security type and password were sufficient.
