Description

It looks like the crash occurs on line:
$.each(self.get("group_list"), function(_, group) {
in nodes-ember.js when Pcs.resourcesContainer.group_list is not an array. This should be easy to fix. We can return an empty list from the groups_enum function if we cannot get the groups. But it would be better to fix the issue at its roots instead of where it manifests itself.
Ondrej, can you take a look at this and fix it in the place where the fix fits the best? Thanks!
Upstream patch: https://github.com/ClusterLabs/pcs/commit/51580b1b38745b29e97229a2e938694ac4166b8 TEST: 2-node cluster, nodes: rhel7-node1, rhel7-node2 Open nodes page of tested cluster from web UI of node which is not part of the cluster.
