With v2.6.1 and MTV-1063  the UI does now allow for selection of net-attach-defs from the default namespace.

However, upon saving the plan this error prevents execution:

Danger alert:The plan is not ready - NetworkMapNotReady

Map.Network does not have Ready condition.. To troubleshoot, check the Forklift controller pod logs.

 
The generated networkmap can not find the NAD.

It does exist in default

$ oc get net-attach-def vlan-1924 -n default
NAME        AGE
vlan-1924   40d
$ oc get net-attach-def -n openshift-mtv
No resources found in openshift-mtv namespace.

 
Multus will require the proper namespace in the spec. i.e. `openshift-mtv/vlan-1924` above won't work. `default/vlan-1924` should be specified to the pod.
