Then i read the code of senlin-dashboard, i found that belowed :
In this file : https://github.com/openstack/senlin-dashboard/blob/master/senlin_dashboard/api/senlin.py
line 362: return [Node(n) for n in nodes], has_more_data, has_prev_data in fun node_list
and in this file : https://github.com/openstack/senlin-dashboard/blob/master/senlin_dashboard/cluster/clusters/tabs.py
line 74: cluster_nodes = senlin.node_list(self.request,
cluster_id=cluster_id) in fun get_nodes_data
And i change it(line 74) to cluster_nodes, self._more, self._prev = senlin.node_list(self.request,
cluster_id=cluster_id)
Finally, thie nodelist of the cluster appeared soon
Fix proposed to branch: master
