Fixed in git commit http://git.fedorahosted.org/git?p=luci.git;a=commit;h=78f9f3c7c7737a896fd77128deba4f3b15f9586a

I can see following error (accompanied by 500 error in browser). That one happens when clicking through my added cluster -> click first (and only) node -> configure -> (network tab) apply.

cluster.conf:
<cluster  name="Z_Cluster4" config_version="3">
 <clusternodes>
    <clusternode name="z4" nodeid="2"/>
 </clusternodes>
</cluster>

*** Bug 683030 has been marked as a duplicate of this bug. ***

I need a response to comment 15, to feel comfortable verifying this.

I've never seen the error mentioned in comment 15 happen. It looks like something went wrong that's unrelated to this feature. The cluster model object is None here (causing the exception), possibly due to a network/connection failure that wasn't properly reported. Are you able to reproduce?

Actually, disregard the comment above. The object that is None is cman_ptr, which should not happen. There's a one line patch that's needed for the case where there is no <cman> element in the cluster.conf.

An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
on therefore solution and/or where to find the updated files,
