Adding metadata to an iControl object using pycontrol

I am trying to add custom metadata to a virtual address using pycontrol. None of my calls fail, but get_metadata always returns an empty list. Here is my program: from pycontrol import pycontr...

    I'm using bigsuds instead of pycontrol, but I was able to get the following to work on 11.3 and 11.5.3. 

    import bigsuds

b = bigsuds.BIGIP(hostname='1.2.3.4')
vip = b.LocalLB.VirtualAddressV2.get_list()[0]

b.LocalLB.VirtualAddressV2.add_metadata([vip], [['owner']], [['daryll']])
vip_metadata = b.LocalLB.VirtualAddressV2.get_metadata([vip])

for meta_data in vip_metadata:
    print b.LocalLB.VirtualAddressV2.get_metadata_value([vip],[[meta_data]])

    If you are at the CLI of the bigip and run 'tmsh save sys config', then you should see metadata attached to the vip. Something like this in /config/bipip.conf:

    ltm virtual-address /Common/192.168.1.41 {
    address 192.168.1.41
    mask 255.255.255.255
    metadata {
        owner {
            value daryll
        }
}

    Perhaps there is an issue with pycontrol? I used only bigsuds. Please let me know how that works out for you.

Thank you. This indeed worked when I switched to the bigsuds library. The API is similar enough that it is less work for me to port my code to bigsuds than diagnose the issue with pycontrol.
