"Error: source_type" when trying to create a loadbalancer

This bug still around, but I think that things are moving to octavia anyways. It's unlikely it will be addressed

Is this related to bug #1621403 ?

On top of my horizon newton installation I am trying the following:

pip install --upgrade pip
pip install oslo_log
pip install neutron-lbaas-dashboard
cp /usr/local/lib/python2.7/dist-packages/neutron_lbaas_dashboard/enabled/* /usr/share/openstack-dashboard/openstack_dashboard/local/enabled/
/usr/share/openstack-dashboard/manage.py collectstatic --noinput
/usr/share/openstack-dashboard/manage.py compress --force
service apache2 restart

Looks like I have no problem importing the panel:

Python 2.7.12 (default, Nov 19 2016, 06:48:10)
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from neutron_lbaas_dashboard.dashboards.project.ngloadbalancersv2 import panel
>>>

I am getting this error when I try to create a new load balancer:

in /var/log/horizon/horizon.log

2017-03-13 12:38:18,591 29 WARNING horizon.exceptions Recoverable error: 'source_type'

The system has already some LBaaSv2 that I can list with the CLI doing
neutron lbaas-loadbalancer-list

(neutron) lbaas-loadbalancer-list
+--------------------------------------+-------+-------------+---------------------+----------+
| id | name | vip_address | provisioning_status | provider |

+--------------------------------------+-------+-------------+---------------------+----------+
(neutron)

BUT the Horizon panel is always empty and does not show this load balancer.

My versions:

neutron-lbaas==8.3.0
neutron-lbaas-dashboard==2.0.1.dev4

I don't think it's a duplicate. The panel is there, I can create the LB, but after clicking on the Launch button,
"Error: source_type"
"Error: Unable to launch loadbalancer named "lb1"."
appears in Horizon.

Btw, the version is current HEAD from stable/ocata (with Horizon from Ocata).

Ok, seems only the "old" lbaasv2 dashboard is affected, so simply use the ngloadbalancersv2 panel.

Install just the
openstack_dashboard/enabled/_1481_project_ng_loadbalancersv2_panel.py
and not the
openstack_dashboard/enabled/_1480_project_loadbalancersv2_panel.py

Thanks for the help.

It works fine when using ngloadbalancersv2 in ocata, i'll test it for newton also. If i understand correctly, old panel is not longer used, right?

I guess it is more like no longer maintained. But you don't need two panels for the same job, right? Both are GUIs for the lbaasv2 API.

Yes, that's my understanding also. I wonder why the old one is not just removed from the repo.
