Description of problem:
I registered a machine using RHSM and was trying to add a package on newly registered system. I selected the system and on right pane under "packages" tab I found "ADD and "Remove" options. 

Without specify the package name, Add and Remove options were active and when I clicked on it, following notification generated:

>> Success 	Install of Packages '' scheduled for System 'dhcp201-107.englab.pnq.redhat.com'.

Notice that no package name is here between the quotes.

Also following logs generated in production.log:
