Parth Jagirdar commented on CLOUDSTACK-5681:
--------------------------------------------
Santhosh,
Yes network can be created through UI.
Can you do following to try and reproduce?
Go to DB and change the CIDR field in networks to NULL.
Then try to view networks in UI. (listNetworks).
Exception should be thrown there.
This issue was encountered while performing validation in a case where networks
are created though scripts. (Now for API CIDR is not a required param).
And for networks without CIDR, listNetworks and createNetwork(Thorugh Instance
creation wizard) will throw exception.
So to repro you will need to CIDR to NULL in DB.
