Template linkage hierarchy:
vmnode01.tf.nn (host)
\ TF_node_t (template)
\ vnc_t (template)

At TF_node_t level, "vnc_t: VNC is unavailable" depends on "vnc_t: Ping failed (displayed as 'depends on: TF_node_t : Ping failed')".
At vmnode01.tf.nn, the dependency is correctly displayed as "depends on: vmnode01.tf.nn: Ping Failed".

I delete this dependency from TF_node_t - it's deleted from the host as well.
Now I reintroduce it at vnc_t level. It reappears in TF_node_t but not in vmnode01.tf.nn. It does reappear in vmnode01.tf.nn when I unlink and re-link it against TF_node_t.
