[ubuntu:2285]:Horizon:while trying to delete Router from N/w toplogy page ,its stuck at the same state

[Ruchi Priya]

In the N/w topology page when I try to delete a router ,it gets stuck there and fails to delete.
I can very well delete from the Router page.

For an instance if I attempt to delete from the N/w topology page it again gets stuck at the same state but it does delete the instance

Please find the screenshot attached
