when ngimages is set as default panel, page loops infinitely

[Michael Xiong]

Steps to reproduce the issue:
1. Comment out https://github.com/openstack/horizon/blob/master/openstack_dashboard/enabled/_1020_project_overview_panel.py#L21

# DEFAULT_PANEL = 'overview'

This disables 'overview' as being the default panel of project dashboard.

In https://github.com/openstack/horizon/blob/master/openstack_dashboard/enabled/_1051_project_ng_images_panel.py

2. Set DISABLED = False
3. Add line: DEFAULT_PANEL = 'ngimages'

4. Load the project dashboard.
The ngimages panel will reload itself infinitely. I set a debug point in the images.module.js and saw that the loading of js modules would occur again and again, but the page itself wouldn't load.

Keep in mind that https://review.openstack.org/#/c/339122/ will change the route associated with the Angular images. If you check out that code and perform the same changes, what is the result?

https://review.openstack.org/#/c/339164/ is actually the patch where NG Images is live.

I think in this case, the DEFAULT_PANEL optimization now serves the angular.html template (which contains an ng-view) when the URL is "/project" instead of "/project/images". Because of that optimization on the server side, the client side never registers a "/project" route and fallsback on the "otherwise" reload registered by app.module.js.

The question is how to gracefully support this with Angular panels so that they don't need to be modified just because the enabled file now makes a panel a default panel for a dashboard?

[Tyr Johanson (tyr-6)]

Thinking a bit more about this, I think a good long-term fix would be to change Django to redirect "/project" to the full URL "/project/images"
