vCO Bug - Maintenance mode?

Hi,

I'm finding that the "Exit Maintenance Mode" workflow element isn't working. If I place a host into maintenance mode (clearly working, from vSphere client) and then try running the workflow, it doesn't see the host as being in maintenance mode.

I've tried writing my own scriptable task:

var ConnectionState = host.runtime.inMaintenanceMode;
System.log(ConnectionState);

[2014-09-02 09:45:14.393] [I] false

The result of this is always False.

Any ideas?
